Reduce the application of phosphorus fertilizer in peanut fields and improve its efficiency by using iron modified biochar to adsorb phosphorus recovery products.

Introduction: To address the scarcity of agricultural phosphorus (P) fertilizers and reduce phosphorus accumulation in wastewater, this study employed iron-modified biochar (Fe-B) to adsorb phosphorus from water. The phosphorus-loaded iron-modified biochar (Fe-BP) was subsequently applied to peanut fields. Batch experiments were conducted to determine the optimal adsorption parameters and mechanism of Fe-B for phosphate ions (PO ).

Optimizing biochar application for enhanced cotton and sugar beet production in Xinjiang: a comprehensive study.

Background: Optimizing biochar application is vital for enhancing crop production and ensuring sustainable agricultural production. A 3-year field experiment was established to explore the effects of varying the biochar application rate (BAR) on crop growth, quality, productivity and yields. BAR was set at 0, 10, 50 and 100 t ha in 2018; 0, 10, 25, 50 and 100 t ha in 2019; and 0, 10, 25 and 30 t ha in 2020.

A combined approach using slightly acidic electrolyzed water spraying and chitosan and pectin coating on the quality of the egg cuticle, prevention of bacterial invasion, and extension of shelf life of eggs during storage.

Slightly acidic electrolyzed water (SAEW) is often used on eggs to remove microorganisms, but the cuticle will be damaged, causing bacterial invasion and deterioration of egg quality during preservation. Therefore, a combination of SAEW disinfection with chitosan (CS) and pectin (PT) composite coating (CS + PT) was tried in preventing bacterial invasion and prolonging the shelf life of eggs. The results showed the order of decontamination effectiveness on contaminated eggs was SAEW > Electrolyzed reduced water (ERW) + SAEW > ERW > deionized water.
