SIMPLE CORRECTION METHOD OF SOIL PENETRATION RESISTANCE FOR SOIL WATER CONTENT [PDF]

Engenharia Agrícola, 2022
Soil penetration resistance (PR) assessment is a physical assessment of soil to identify compacted soil layers. Its results are influenced by soil moisture. In this study, a method for correcting PR as a function of soil water content is proposed.

Chemical attributes of a remineralized Oxisol [PDF]

Ciência Rural, 2017
ABSTRACT: Remineralizers are comminuted rocks that are applied to soil, and their use as an agricultural amendment was regulated in Brazil in 2013. However, mechanisms of action of these materials must be better known to enable them to be best used in agricultural fields.

Improvement of Phosphate Fertilization Method in Wetland Rice [PDF]

, 2013
The low efficiency of Phosphate fertilization on wetland rice may be overcame by using quickly dissolve P fertilizer. However, for soils containing high dissolve Fe, such as Alfisol and Oxisol, will induce the formation of Fe-P bonding. Therefore, to use
