In organic agriculture, one of the most important factors that ensure the harvest is a healthy soil. Thus, farmers, through the activities they carry out, must aim to ensure optimal amounts of food for the microorganisms in the soil, but also for the plants.
Organic fertilizers are important, but they should be administered only after testing the soil and determining its composition (pH, humus content, amount of phosphorus, potassium, etc.).
Fertilization must not be done in the middle of summer, but rather in spring and autumn.
When it comes to spring fertilization, perfect timing is essential, since early application of fertilizers can compromise your entire crop. Plants begin to grow naturally after the end of the winter vegetation cycle, due to preserved reserves of carbohydrates. In addition, if you have already fertilized the soil in the previous fall, fertilizers will still do their job during spring. Therefore, spring fertilization should be done by the end of May.
On the other hand, fall fertilizer is also vital for plants, since it can provide the soil and the crops with all the nutrients consumed in the warm season. The main advantage of fertilizing the soil in autumn is the gradual release of nutrients from the compost into the soil, until the beginning of spring, when the plants will begin to extract these substances in order to develop optimally.
