The increasing emission of greenhouse gases such as CO2, CH4, and N2O from the soil has become a growing concern globally. To address this issue, biochar emerged an environmentally friendly amendment that can affect gas permeability reduce emissions. biochar-soil-plant system exhibits complicated interaction promotes plant productivity root elongation, further impacting objective paper is to provide comprehensive review effects on consequently in vegetated soil. begins by discussing basic characteristics its impact microstructure. It then explores both non-vegetated mechanisms through which influences are explained terms modified aeration, water holding capacity, adsorption, pH, available nutrients, activity microbes enzymes. role plants biochar-amended also analysed comparing group with non-vegetation group. includes discussion various methods used measure permeability, steady-state transient methods, well measurement techniques, chamber micrometeorological methods.

In order to increase the crop water productivity (WPc) of agricultural systems, and support farmers in minimizing uncertainty availability, we conducted a three-years experiment commercial adult mandarin orchard quantify effect sustained severe deficit irrigation combination with use geotextile mulch on agronomic physiological response crop. For this purpose, five treatments were tested: (i) control (CTL) irrigated at 100% evapotranspiration (ETc) during entire season; ii) (SDI), ∼70% CTL; (iii) regulated (RDI), as SDI, except initial period second fruit growth stage, when trees 35% CTL, maintaining moderate stress level around –1.5 MPa stem potential (Ψs), until fruits reached 70% their final size. addition, two established, using same criteria SDI RDI treatments.

Crop diversification can enhance farm economic sustainability while reducing the negative impact on environment and ecosystem services related. Despite market non-market benefits of crop diversification, monocropping is a widely used dominant practice in Europe. In this context, works aims to assess overall several systems across Europe compared it system.

Given the current degradation problems that Mediterranean soils endure, implementation of alley cropping in olive orchards has been suggested as a sustainable strategy to increase agricultural productivity and improve carbon storage soil fertility. Therefore, objective this study was evaluate short term (3 years) effect with minimum tillage versus conventional traditional rainfed grove on organic carbon, total nitrogen concentrations, stocks. Changes quality through stratification index, success 4‰ these type management were also evaluated. Three intercropping strategies tested: Crocus sativus (D-S), Vicia sativa Avena rotation (D-O), Lavandula x intermedia (D-L), all without intercropping, which used control. Intercropping increased topsoil (0–10 cm) by 41.1, 28.5, 30.5% for D-S, D-O, D-L, respectively, compared tillage. At depth 10–30 cm, stock slightly, although significant differences found only D-L. In diversified plots, did not vary. However, due fertilisation. Concerning quality, no observed when evaluating index any treatments. reached objectives set initiative an per hectare year 80, 87.4, 86.4% respectively. based results, term, treatment enhances soils, effectively achieving initiative.

Abstract Effective and large-scale monitoring of agroforestry (AF) systems is essential to assess the environmental benefits support sustainable land management strategies. However, a standardized method for classifying these using satellite imagery still missing. Here, we present novel operational framework classify into three categories—Alley cropping, Scattered agroforestry, Hedgerows—and distinguish from Cropland without trees, Natural Orchards. The proposed procedure relies on classification tree based photo-interpretation imagery. accuracy robustness this were evaluated by five interpreters across 300 non-agroforestry plots spanning all continents. Results show that accurately distinguishes categories one another systems, with an overall ranging 0.75 0.81 depending interpreter. After eliminating interpreters’ errors, potential increases 0.86. While hedgerows classified in most cases omission error 2% no commission (0%), study revealed challenges differentiating between Alley cropping Orchards which frequently confounded. Similarly, also misclassified as trees leading 19% class. Despite limitations, represents valuable tool systems. Future adaptations could address regional specificities, further improving its applicability accuracy.
