The South-Eastern Nigeria has heavy annual rainfall and at riskof leaching by acid rain hence there is a strong need to study the acidity of water from this zone as determine it’s effect on fertilizer components applied soil pH affect nutrient retention. was therefore conducted application agricultural soils in Umuahia one cities South-East. Agricultural collected Umudike designated Soil(UAS).T...

potassium (k) is an essential element for plant growth and development and its importance in agriculture is well known. it plays an important role in improving the quality of agricultural products. besides, micaceous minerals are abundant in iranian soils. the role of plant species in potassium uptake from minerals is significant; but not well investigated. therefore, the objective of this rese...

Objective: To evaluate the residual effect of gypsum in corn crops (2 years after its application a previously limed soil), as well result new addition combined with potassium La Frailesca, Chiapas, Mexico. Design/Methodology/Approach: We used composite factorial design. The initial arrangement (2017) consisted four levels (0, 1.25, 2.5, and 5 t ha-1) 60, 120, 180 kg K2O ha-1). In 2019, gypsum-...

For the development of measures for rational use soils, an agrochemical assessment soils is important. The purpose research was to establish dynamics changes in soil fertility indicators Chernivtsi region during 2011-2020. In our work were used laboratory and field methods, analysis generalization. samples, reaction environment, humus content, nitrogen content easily hydrolyzable compounds, mob...

Soil salinization is a significant obstacle to agricultural development in arid and semiarid regions. While short-term experiments have demonstrated the effective improvement of saline soils through biochar amendment, long-term efficacy sustainably ameliorating such remains uncertain. Addressing this knowledge gap, study investigated effects amendment field setting by applying different rates s...

Potassium (K) is a primary macronutrient for overall plant growth, yield potential, product quality and stress resistance of crops. Potato (Solanum tuberosum L.) crops require high amount potassium to achieve the ideal quality. Therefore, determination optimum K rate efficient source potato necessary because affects crop physiological processes, dry matter production, cooking, processing requir...
