Organic fertilizers contain all nutrients a plant needs in contrast to mineral fertilizers. In general it is manure that contains the nutrients, but not all elements are directly available for the plant. The part that is active is called the coefficient. For nitrogen, there is a mineral and organic concentration present in manure. The mineral concentration is available for the plant and the organic concentration will be released step by step, because of the demolition of organic matter in the soil.
Application of organic fertilizers
Komeco has carried out various tests on agricultural fields and they have shown that 60% of the nitrogen from FERTISOL will become available during the crop cycle. Within the first week half of it will be released already. More nitrogen will be released during the growth. It does depends of the crop itself. For example carrots can absorb more nitrogen than grains because the uptake period of carrots is longer. The tests have shown that 40% of the phosphate and 85% of the potassium in FERTISOL will be released during the crop cycle as well.
During cultivation we have observed the crops and we can conclude that the crop remained vital for a longer period. The leafs remained greener (results of observations in a plot of potatoes).
Both manure and organic fertilizers contain nitrogen, phosphate and potassium, but the levels can vary per batch enormously. That is why spreading manure in a plot cannot guarantee the exact levels of N-P-K. Something which is more certain by using organic fertilizers. At Komeco we mix the manure well during the controlled composting process. Therefore the composition is homogeneous and it creates pellets offering the right nutrients for every crop and plant.
