Arbuscular mycorrhizal fungi (AMF) form symbiotic relationships with the roots of nearly all land-dwelling plants, increasing growth and productivity, especially during abiotic stress. AMF improves plant development by improving nutrient acquisition, such as phosphorus, water, mineral uptake. tolerance resilience to stressors drought, salt, heavy metal toxicity. These benefits come from arbuscular interface, which lets fungal partners exchange nutrients, signalling molecules, protective chemical compounds. Plants' antioxidant defence systems, osmotic adjustment, hormone regulation are also affected infestation. responses promote performance, photosynthetic efficiency, biomass production in stress conditions. As a result its positive effects on soil structure, cycling, carbon sequestration, contributes maintenance resilient ecosystems. The AMFs ecological stability species- environment-specific.

Spaceborne imaging spectroscopy is a highly promising data source for all agricultural management and research disciplines that require spatio-temporal information on crop properties. Recently launched science-driven missions, such as the Environmental Mapping Analysis Program (EnMAP), deliver unprecedented from Earth's surface. This new kind of should be explored to develop robust retrieval schemes deriving crucial variables future routine missions. Therefore, we present workflow inferring carbon content (Carea), aboveground dry wet biomass (AGBdry, AGBfresh) EnMAP data. To achieve this, hybrid was generated, combining radiative transfer modeling (RTM) with machine learning regression algorithms.

Currently, growth in agricultural production not sufficient to keep up with growing population, which may result a shortfall world’s inhabitants. As result, increasing crucial developing nations limited land resources. It essential select suitable crop specific region increase its rate. Effective forecasting that area based historical data, including environmental cultivation areas, amount, required. However, data such are publicly available. such, this paper, we take case study of country, Bangladesh, whose economy relies agriculture. We first gather preprocess from relevant research institutions Bangladesh then propose an ensemble machine learning approach, called K-nearest Neighbor Random Forest Ridge Regression (KRR), effectively predict major crops (three different kinds rice, potato, wheat).

To optimize agricultural land management for soil carbon sequestration, it is necessary to identify whether agroecosystems are accumulating or gaining carbon. This can be done by determining an agroecosystem's net ecosystem productivity (NEP). study collated data from 40 papers, containing 242 annual measurements of NEP, assess the impact climate, type and on NEP croplands managed grasslands. Croplands lost significantly more (110 g Cm−2) than grasslands (29.9 there was little statistical influence soil, practice NEP.
