Soil Fertility Management for Better Crop Production

open access: yesAgronomy, 2020
Increasing crop productivity per unit of land area to meet future food and fiber demand increases both soil nutrient removal and the importance of replenishing soil fertility through efficient nutrient management practices.

Soil Testing for Plant-Available Nutrients—What Is It and Why Do We Use It?

open access: yesEDIS, 2014
Farmers need soil-testing procedures to assess soils for potential plant-available nutrients. Soil testing is the foremost best management practice (BMP).

Integrated Effect of Organic Amendments and Chemical Fertilizers on yield of Groundnut and Soil Health Under Rainfed Condition

open access: yesJournal of Applied Research in Plant Sciences
Although inorganic fertilizers increase the growth of crops, but their toxicity is the main concern due to their over utilization. To tackle this problem, the integrated application of organic amendment especially vermicompost, with NPK fertilizers would

Effect of X-Ray Tube Configuration on Measurement of Key Soil Fertility Attributes with XRF

open access: yesRemote Sensing, 2020
The successful use of energy-dispersive X-ray fluorescence (ED-XRF) sensors for soil analysis requires the selection of an optimal procedure of data acquisition and a simple modelling approach.

Soil testing for P and K has value in nutrient management for annual crops

open access: yes, 2016
Adequate nutrients in forms available to plant roots are essential for sustainable crop production. Soil testing for phosphorus and potassium availability allows growers and crop advisers to determine whether a soil is likely to respond to fertilization.

Phosphorus Fractions in Temperate Grassland Soils and Their Interactions with Agronomic P Tests

open access: yesAgronomy, 2022
Phosphorus (P) is a major nutrient for plant growth and animal health, and its availability in soil is influenced by agronomic management and soil properties. This study examined the distribution of labile and non-labile soil P fractions in grassland and

Plant growth and phosphorus uptake of coffee seedlings through mycorrhizal inoculation

open access: yesAgronomía Colombiana, 2022
Soil phosphorus (P) availability is a limiting factor for coffee seedling growth. Usually, large amounts of P fertilizers are required, generating nutritional imbalance, increasing production costs, and raising environmental concerns in water pollution.
