Organic fertilizer is a fertilizer made from livestock and poultry manure through high-temperature fermentation, which is very effective for soil improvement and promotion of fertilizer absorption.
To produce organic fertilizer, it is best to first understand the characteristics of the soil in the area where it is sold, and then according to the soil conditions in the area and the nutritional needs of the applicable crops, scientifically mix the raw materials such as nitrogen, phosphorus, potassium, trace elements, fungi, and organic matter to produce to meet the user And ensure the stickiness and reasonable profit of farmers.
For the nutrient requirements of the following cash crops: The data comes from the Internet for reference only
1. tomato:
According to measurements, for every 1,000 kg of tomatoes produced, 7.8 kg of nitrogen, 1.3 kg of phosphorus, 15.9 kg of potassium, 2.1 kg of CaO, and 0.6 kg of MgO are required.
The order of absorption of each element is: potassium>nitrogen>calcium>phosphorus>magnesium.
Nitrogen fertilizer should be the mainstay in the seedling stage, and attention should be paid to applying phosphorus fertilizer to promote the expansion of leaf area and the differentiation of flower buds.
As a result, in the peak period, the amount of fertilizer absorption accounted for 50%-80% of the total absorption. On the basis of sufficient nitrogen and potassium supply, phosphorus nutrition must be increased, especially for protected cultivation, and more attention should be paid to the supply of nitrogen and potassium. At the same time, carbon dioxide gas fertilizer, calcium, magnesium, boron, sulfur, iron and other medium elements should be added. Combined application with trace element fertilizers can not only increase yield, but also improve its quality and increase commodity rate.

Loofah grows fast, has many fruits, and is fertile. It takes 1.9-2.7 kg of nitrogen, 0.8-0.9 kg of phosphorus, and 3.5-4.0 kg of potassium from the soil to produce 1,000 kg of loofah.
19. Kidney Beans:
Nitrogen, kidney beans like nitrate nitrogen fertilizer. The more nitrogen is not the better. Appropriate application of nitrogen is beneficial to increase yield and improve quality. Too much application will cause flowering and delayed maturity, which will affect the yield and benefit of kidney beans. Phosphorus, phosphorus plays an important role in the formation and flowering and pod formation of kidney bean rhizobia.
Phosphorus deficiency tends to cause the growth and development of kidney bean plants and rhizobia, reducing the number of flowering pods, fewer pods and grains, and lower yields. Potassium, potassium can obviously affect the growth and development of kidney beans and the formation of yield. Insufficient supply of potassium fertilizer will reduce the production of kidney beans by more than 20%. In terms of production, the amount of nitrogen fertilizer should be more appropriate. Even if the amount of potassium is less, the symptoms of potassium deficiency will generally not appear.
Magnesium, kidney beans are prone to magnesium deficiency. If there is insufficient magnesium in the soil, starting from 1 month after sowing of kidney beans, first in the primary leaves, as the chlorosis starts between the veins of the first true leaf, it will gradually develop to the upper leaves, which lasts about 7 days. It starts to fall off and the yield decreases. Molybdenum, a trace element Molybdenum is an important component of nitrogenase and nitrate reductase. In physiological metabolism, it mainly participates in biological nitrogen fixation and promotes the nutrient metabolism of nitrogen and phosphorus in plants.
20. pumpkins:
Pumpkin’s nutrient absorption and absorption ratio are different in different growth and development stages. The production of 1000 kg of pumpkins needs to absorb 3.5-5.5 kg of nitrogen (N), 1.5-2.2 kg of phosphorus (P2O5), and 5.3-7.29 kg of potassium (K2O). Pumpkins respond well to organic fertilizers such as manure and compost
