Impact of long-term phosphorus and potassium fertilization on alfalfa nutritive value–yield relationships
Phosphorus (P) and potassium (K) increase alfalfa (Medicago sativa L.) yield, but little information is available on how forage nutritive value is affected by P and K fertilization. The objective of this study was to investigate the effect of long-term P and K fertilization on alfalfa yield–forage nutritive value relationships. A factorial experiment with four P and five K treatments was ...

Nitrogen increases evapotranspiration and growth of a warm-season turfgrass
The effect of N fertilizer rate on Kikuyu turfgrass [Pennisetum clandestinum (Hochst. ex Chiov)] evapotranspiration was evaluated during two summers. Evapotranspiration was measured using weighing lysimeters (205 mm in diameter by 625 mm in length) inserted in turfgrass field plots (10 m2). The experiment was a randomized plot design with three replicates. Treatments included two turfgrass ages ...

Drying process of NPK manufacturing process
There are two conditions for the drying of NPK manufacturing process: temperature and air volume. If the inlet temperature of dryer (500 ~ 6000c) is too high, the material in dryer will change greatly. Because the decomposition and solubility of materials are related to temperature. Due to the decomposition of chemical fertilizer or the increase of solubility, the liquid phase of materials in the ...

Why organic fertilizer equipment is suitable for small investment
In agricultural production, in order to achieve the increase of crop production, people do not hesitate to pour a large number of chemical fertilizer into the farmland. More and more nitrogen, urea and nitrogen, phosphorus, potassium compound fertilizer are used, and the concentration is higher and higher. Although this has kept the effect of increasing production to a certain extent, the ...

Top 10 Advantages of Organic Fertilizers for Agriculture and Farming
Fertilizers supplement the nutrients already present in the soil. The fertilizing products can be vaguely classified as Organic or Natural Fertilizers and Synthetic or Man-Made Fertilizers. While synthetic or chemical fertilizers are concentrated, strong and quick enough to dissolve in the soil immediately, Organic Fertilizers for plants release nutrients slowly with time and often contain many ...
