Crop damage identification

Posted on

Crop fertilizers identify excessive fertilizers or fertilizers used are not the right way, the crops are prone to fertilizer damage. The main characteristics of crop damage are dehydration, burns and poisoning. Corresponding measures can be taken according to the crop's performance on the damage: 1. Excessive dehydration and fertilization, or excessive drought in the soil, causing high local soil concentration after fertilization, leading to crops Loss of water and a state of wilting. 2. Burning In the hot sun, apply volatile fertilizers (such as ammonium bicarbonate, etc.) to burn the leaves or young tissues of the crops (burning seedlings). 3. The content of "biuret" in toxic urea is more than 2%, or the free acid content in superphosphate is higher than 5%. After applying it into the soil, it causes root poisoning of the crop to rot; applying a relatively large amount of organic fertilizer without decomposition, Because of its decomposition and fever and the release of harmful gases such as methane, causing damage to crop seeds or roots.
