Take chemical fertilisers, which deliver nitrogen, an essential plant nutrient, to crops along with some phosphorus andpotassium. It is a mantra of organic farming that these fertilisers are unwholesome, and plant nutrients must come from natural sources. But in fact, the main environmental damage ...

fertilization with nitrogen and potassium12,13. Different works towards method innovations in soil fertility managing and incentive development for crop straw combined with natural fertilizer applications are required14. The application of compost manure significantly improved the grain yield of maize15. Com...
3. Activate fertilizer. Nitrogen in the soil most likely to churn, and phosphorus, potassium is not easy to absorb, the product of strong-motion function can be activated phosphorus, potassium, and surrounded by "N", thereby improving fertilizer utilization. 4. ripper promote root. This ...
Granular Revive is made with DPW (Dehydrated Poultry Waste) containing primary plant foods that have a low burn potential. The result is a slow-release, non-burning organic-based fertilizer that saves water.Nitrogen Phosphorus and Potassium 5-1-1. ...
Use efficiency of nitrogen, phosphorus and potassium in organic fertilizer were limited between 7.37%~9.51%, 1.49%~4.39%, 9.10%~15.32% respectively. With increase of organic fertilizer rate, there was no markedly effect in promoted the nutrient absorption. nutrients use efficiency decreased and the...
Organically derived fertilizers typically have a lower NPK analysis (nitrogen, phosphorus, potassium) than synthetics fertilizers, but they feed plants for a much longer period of time. As a result, the impact of organic fertilizers on lawn and plants is usually more subtle. It may take a littl...
For nitrogen, plant meals and animal byproducts like bat guano and fish emulsion typically provide the most nutrient. Bone meal and rock phosphate are the best organic sources for phosphorus. Alfalfa pellets and some kelp products are the best bet for supplementing potassium. ...
The laboratory and field experiments of microbial organic fertilizer application were undertaken to test the effects on maize production and organic matter,total nitrogen(TN),total phosphorus(TP),available phosphorus(AP) and available potassium(AK) in saline-alkali soil.The results showed that the yiel...
