Reapplication of biochar, sewage waste water, and NPK fertilizers affects soil fertility, aggregate stability, and carbon and nitrogen in dry-stable aggregates of semi-arid soil.

Science of the Total Environment, 2022
Biochar has been applied to increased soil nutrients, especially C. In RCBD, control fresh water (CFW), sewage wastewater (SWW), NPK fertilizer, rice husk biochar (RHB), and NPK + RHB treatments were arranged with four replications.

A comparison between the characteristics of a biochar-NPK granule and a commercial NPK granule for application in the soil.

Science of the Total Environment, 2022
Continual application of nitrogen (N), phosphorous (P) and potassium (K) fertilizer may not return a profit to farmers due to the costs of application and the loss of NPK from soil in various ways. Thus, a combination of NPK granule with a porous biochar

Comparative effects of biochar and NPK on wheat crops under different management systems

Crop and Pasture Science, 2022
As a multi-beneficial amendment, biochar is very useful to be applied for improving soil health and crop productivity. Therefore, this study was carried out to assess the influence of wood biochar and mineral nitrogen (N), phosphorus (P) and potassium (K)

Determination of soil nutrients (NPK) using optical methods: a mini review

, 2021
In the present situation, plants have to meet the food supply demand for a large and increasing population. In order to get high yield, it is essential for the plantations to be nourished with soil containing an appropriate amount of nutrients like ...

Nutrient Sensing and Signaling: NPKS

Annual Review of Plant Biology, 2007
Plants often grow in soils that contain very low concentrations of the macronutrients nitrogen, phosphorus, potassium, and sulfur. To adapt and grow in nutrient-deprived environments plants must sense changes in external and internal mineral nutrient concentrations and adjust growth to match resource availability.

Drum granulation of NPK fertilizers

Powder Technology, 2000
Nitrate-based NPK fertilizer was granulated in a bench scale drum granulation unit. The initial fertilizer possessed a particle size distribution similar to those in industrial granulation units. In this work, three factors are identified affecting the degree of fertilizer granulation, these are solution to solid phase ratio, the binder viscosity and ...

Conventional to Modern Methods of Soil NPK Sensing: A Review

IEEE Sensors Journal
In this review, we have evaluated several methods and recent technologies to determine the soil nitrogen, phosphorus, and potassium (NPK) content to increase yield production. Sensing technology has been used for a long time to determine the exact amount
