Establishing desirable cropping systems with higher fertilizer-use efficiency and lower risk of environmental pollution is a promising approach for more sustainable agriculture development. Intercropping may facilitate phosphorus (P) uptake and reduce P-fertilizer application rates. However, how root-root int...

Ensuring that your crops are rich in nutrients like Nitrogen (N), Phosphorus (P) and Potassium (K) is a crucial aspect of a healthy farm. But oftentimes, most of the N, P and K applied to the soil is never absorbed by the crop and does not have a chance to improve crop performance...
The fertilizer with controlled components release comprising shredded, dried and sterilised biomass containing protein from 1,0 to 30% w/w, phosphorus 0,5 to 15% w/w, potassium compound 2 to 25% w/w, sulphur compounds 0,5 to 3,0% w/w, reactive alkaline substances 5 to 40% w/w, ...
Thesetypes of fertilizersare higher in both potassium and phosphorus, which are essential for vigorous flowering. Phosphorus helps spur abundant blooms and fruiting. A fertilizer high in nitrogen will encourage a lot of leaf growth, but lots of phosphorus supports healthy, potent flower buds. ...
The fertilizer with high saline-alkali soil organic matter content comprises the following components in parts by mass: 40-45 parts of organic fertilizer, 30-36 parts of peat, 7-10 parts of vermiculite, 5-6 parts of potassium feldspar, 7-10 parts of fulvic acid, 4-6 parts of humic acid...
Phosphorus fertilizers includecalcium phosphatederived fromphosphate rockor bones. The more soluble superphosphate and triple superphosphate preparations are obtained by the treatment of calcium phosphate with sulfuric andphosphoric acid, respectively. Potassium fertilizers, namelypotassium chlorideand potassium sulf...
【Objective】 The purpose of this paper was to estimate the fate of fertilizer N applied to winter wheat under optimum nitrogen(N),phosphorus(P) and potassium(K) rates in north China plain.【Method】 A field micro-plot experiment was adopted and high abundance of15N was applied to wheat in...
The amount of fertilizer supplied to plants should be effective enough to increase the effective nutrients of the soil absorbed by the plants to increase yield and quality24. Studies have shown that the nutrients in the soil, especially phosphorus (P) and potassium (K), have an important ...
