How should organic fertilizer be applied when growing pollution-free vegetables?
How should organic fertilizer be applied when growing pollution-free vegetables? Please give guidance. When growing vegetables, the concentration of nitrogen in the soil and the type of nitrogen applied directly affect the crop's disease resistance, marketability and nitrate content. Therefore, keeping the soil loose and fertile is a key measure for reducing pests and diseases and achieving high quality and high yields...

What should you pay attention to when choosing organic fertilizer?
What should you pay attention to when buying organic fertilizer? Please note the following points when buying organic fertilizer: 1. The total nutrient content and organic matter content of organic fertilizer. Some inferior organic fertilizers on the market generally find it relatively easy to meet the required total nitrogen, phosphorus and potassium nutrient content (a small amount of chemical fertilizer only needs to be added), but the organic matter content is often not up to standard.

How should phosphate and potassium fertilizers be applied when growing corn?
How should phosphate and potassium fertilizers be applied when growing corn? Please give guidance. When growing corn, the effect of phosphate and potassium fertilizer application varies greatly depending on the soil's available nutrient content. Increasing phosphate and potassium application helps produce strong seedlings that emerge early, strong plants with large ears, a higher grain-to-leaf ratio, and more grains and greater grain weight; it is an important condition for improving population quality. However, after phosphate and potassium fertilizers are applied, ...

What precautions should be taken when using herbicides in farmland?
How should herbicides be applied to chive seedlings? Please advise. Chives are relatively sensitive to acetochlor, so acetochlor should not be used for soil-closure treatment. After sowing chives and before emergence, prometryn, pendimethalin, and butralin can be used for soil-closure treatment. Among them, prometryn is mainly used to control broadleaf weeds, while pendimethalin and butralin...

What points should be noted when applying phosphate fertilizer?
What effect does nitrogen fertilizer have on wheat? Please explain that among the elements required for wheat growth and development, nitrogen has the greatest impact on wheat grain quality, and its grain yield and protein content depend to a large extent on the level of nitrogen supplied by the soil. If the supply is very sufficient throughout the entire growth period of wheat, wheat will be both high-yielding and high in protein...
