Humic fertilizer

Humic fertilizer. Humic fertilizer are complex organic molecules that are formed by the breakdown of organic matter. Humic fertilizer influences soil fertility through its effect on the water-holding capacity of the soil. Humic fertilizer make important contributions to soil stability and soil fertility leading to exceptional plant growth and micro nutrient uptake.

There has been much interest in the subject of soil Humic fertilizer, humus and humates over the years. There is basic agreement on the benefits of humus. Humic fertilizer are reported to increase the permeability of plant membranes, so promoting the uptake of nutrients. There is evidence of a positive effect of Humic fertilizer substances on the growth of various groups of microorganisms. There is also evidence that some of the humate materials contain large populations of Actinomycetes (microorganisms that share the properties of both fungi and bacteria). They are capable of degrading a wide range of substances including celluloses, humicelluloses, proteins, and lignin.


  • Humic fertilizer physically modify the structure of the soil.
  • Improve the structure of soil: Prevent high water and nutrient losses in light, sandy soils. Simultaneously convert them into fruitful soils by way of decomposition. In heavy and compact soils, aeration of soil and water retention are improved; cultivation measures are facilitated.
  • Humic fertilizer prevent soil cracking, surface water runoff and soil erosion by increasing the ability of colloids to combine.
  • Humic fertilizer help the soil to loosen and crumble and thus increase aeration of soil as well as soil workability.
  • Humic fertilizer increase water holding capacity of soil and thus help resist drought.
  • Humic fertilizer darken the color of the soil and thus help absorption of the sun energy.

The Secrets of Foliar Spraying

Foliar feeding is a method of fertilizing plants directly. It involves directly spraying Foliar Spraying, what is a foliar spray, organic foliar spray, best foliar spray, foliar spray fertilizer, spraying fertilizer,nutrients onto the plants leaves and stem where they are absorbed and used. It is considered an almost immediate way to feed your plants. It is becoming very common especially among small gardeners and lawn owners. It has a several advantages and disadvantages which include the following.

Foliar Fertilization is the most efficient way to increase yield and plant health. Tests have shown that foliar feeding can increases yields from 12% to 25% when compared to conventional fertilization. Tests, conducted in different locations, under different environmental conditions, have reflected the following;

  • When fertilizers are foliar applied, more that 90% of the fertilizer is utilized by the plant. When a similar amount is applied to the soil, only 10 percent of it is used.
  • In the sandy loam, foliar applied fertilizers are up to 20 times more effective when compared to soil applied fertilizers.

Foliar feeding is an effective method for correcting soil deficiencies and overcoming the soil’s inability to transfer nutrients to the plant under low moisture conditions. The effectiveness of foliar applied nutrients is determined by

  • The condition of the leaf surface, in particular the waxy cuticle. The cuticle is only partially permeable to water and dissolved nutrients and, as a result, it can limit nutrient uptake.
  • The length of time the nutrient remains dissolved in the solution on the leaf’s surface.
  • Diffusion, the movement of elements from a high concentration to a low concentration. For diffusion to occur, the nutrient must dissolve, and
  • The type of formulation. Water-soluble formulations generally work better for foliar applications as they are more easily absorbed when compared to insoluble solutions.

More Benefits from Foliar Sprays

Not only do nutritional foliar sprays benefit plants above ground but they also feed soil biology and increase the stock of capital in the “barter system” happening within the rhizosphere. The rhizosphere is that thin covering of soil surrounding roots of a plant that is teaming with life. This is the “marketplace” where the “producers” and the “decomposers” get together and trade with each other. The “producers” i.e. plants trade amino acids and carbohydrates in the form of exudates and mucigel in exchange for dissolved soil minerals. Mucigel is that slimy polysaccharide substance covering roots that helps roots penetrate soil. It is also an excellent food and energy source for bacteria. Soil bacteria must have energy (plant sugars) to survive and “decompose” rock powders to liberate bound up nutrients to “trade” with plants.

When a foliar spray is properly made and applied it will cause an increase of plant sugars. A certain percentage (research suggests 25-30%) of these sugars are used to feed soil biology. Thus the outcome of a proper foliar program results in an extra infusion of “capital” into the “marketplace” of the rhizosphere; more sugars feed the soil biology and thus more soil minerals are taken up by the plant. What an amazing system and Creator!

Using vermicompost as mulch, in the soil or as potting media is beneficial in many ways.

Vermicompost_Manufacturers_Suppliers_Exporters_in_Kolkata_West_BengalVermicompost contains a full spectrum of essential plant nutrients. You can test the nutrient levels in your compost and soil to find out what other supplements it may need for specific plants.

  • Vermicompost contains macro and micronutrients often absent in synthetic fertilizers.
  • Compost releases nutrients slowly—over months or years, unlike synthetic fertilizers
  • Vermicompost enriched soil retains fertilizers better. Less fertilizer runs off to pollute waterways.
  • Vermicompost buffers the soil, neutralizing both acid & alkaline soils, bringing pH levels to the optimum range for nutrient availability to plants.
  • Vermicompost helps bind clusters of soil particles, called aggregates, which give good soil structure. Such soil is full of tiny air channels & pores that hold air, moisture and nutrients.

Compost helps sandy soil keep water and nutrients.

  • Compost loosens tightly bound particles in clay or silt soil so roots can spread, water drain & air penetrate.
  • Compost alters soil structure, making it less likely to erode, and prevents soil spattering on plants—spreading disease.
  • Compost can hold nutrients tight enough to prevent them from washing out, but loosely enough so plants can take them up as needed.
  • Compost brings and feeds diverse life in the soil. These bacteria, fungi, insects, worms and more support healthy plant growth.

Compost bacteria break down organics into plant available nutrients. Some bacteria convert nitrogen from the air into a plant available nutrient.

  • Compost enriched soil have lots of beneficial insects, worms and other organisms that burrow through soil keeping it well aerated.
  • Compost may suppress diseases and harmful pests that could overrun poor, lifeless soil.
  • Compost makes any soil easier to work.
  • Healthy soil is an important factor in protecting our waters. Compost increases soil’s ability to keep water & decreases runoff. Runoff pollutes water by carrying soil, fertilizers and pesticides to nearby streams.

Vermicompost encourages healthy root systems, which decrease runoff

  • Vermicompostcan cut or cut use of synthetic fertilizers
  • Vermicompostcan reduce chemical pesticides since it has beneficial microorganisms that may protect plants from diseases and pests.
  • Only a 5% increase in organic material quadruples soils water holding capacity.

Determining Amounts of Fertilizer over Small Areas

Determining Amounts of Fertilizer over Small Areas. Fertilizers can promote vigorous growth of plants and good production. However, fertilizing will not correct problems related to soil pH, salinity, or presence of sodium . Successful gardening begins with soil testing in order to get the most out of your dollar for fertilizer. A simple soil pH test  can tell you what to do before fertilizing in order to have a successful garden (such as salinity control or managing sodium). Prescription fertilizer recommendations can be made for your specific conditions if your soil is tested.

Proper timing of fertilizer applications will be important once a recommended fertilizer rate is determined from the soil test. Plants vary in their requirements, and soils can contain different amounts of plant-available nutrients based on their history. Fertilizer packaging is required by law to state clearly the percentage nitrogen (N), phosphorus (P2O5), and potash (K2O) by weight. For example, if a container or package reads “16-4-8”, this means that for every hundred kg of this fertilizer there would be 16 kg of nitrogen, 4 kg of P2O5 and 8 kg of K2O. The rest of the weight, all 72 kg worth, is a carrier of the N, P2O5, or K2O. For example, K2O is often present as potassium chloride (KCl) or potassium sulfate (KSO4). The chloride or sulfate helps carry the nutrient of
interest, in this case, potassium (K).

You can also calculate exactly what you need for your specific space with a little practice.

Determine the amount of ammonium sulfate needed by a 1,000 square-foot lawn if the soil test fertilizer recommendation suggests 50 kg of nitrogen per acre.
Lawn: 1,000 square feet
Fertilizer: ammonium sulfate (21-0-0)
Nutrient Rate: 50 kg of nitrogen per acre
Square feet per acre: 43,560

Step 1. Divide kg N per acre by 43,560.
This is the kg needed per square foot.
(50 lb N/Acre) ÷ (1 acre/43,560 sq feet) = 0.00115

Step 2. Multiply by square feet to fertilize. This is the kg of nitrogen needed.
0.00115 x 1,000 = 1.15 lb N
Step 3. Divide the percent N in the fertilizer by 100.
21%N ÷ 100 = 0.21
Step 4. Divide the result in Step 2 by the result in

Step 3.
1.15 ÷ 0.21 = 5.48 kg= 5.8 kg
This is the amount of ammonium sulfate needed over 1,000 square feet to supply an equivalent of 50 lb N per acre. On the other hand, only 2½ kg of urea would be needed since urea contains 46% nitrogen.

From tons to teaspoons

When working with small areas, flower pots, or garden boxes we often switch from using kg to units of volume including pints, cups, tablespoons, and teaspoons. Though it is easy
to over-apply fertilizers in this manner the following tables should help when trying to use fertilizer recommendations based on soil testing. The fertilizer can be mixed with the soil to be put in the pot, or the fertilizer can be dissolved in water and then poured into the pot containing the soil. It is important, however, not to put all the nitrogen or potash material into the pot at one time, especially in liquid form. This can lead to excess salinity in
the pot or loss of nitrogen and potash by leaching.

Slow-release fertilizers should be added in the granular form. Many potting soils are sold with nutrients already mixed into the media, and additional fertilization is often not needed.

Soil test–based fertilizer recommendations are given as weight per unit area. Converting to volume measures means that the fertilizer density needs to be known. Fertilizers do not all have the same density. One cup of urea does not weigh the same as one cup of ammonium sulfate.
