In study, top-tillage samples were collected from 185 maize continuous cropping areas 12 physicochemical indexes (pH, cation exchange capacity (CEC), organic matter (SOM), total nitrogen (TN), phosphorus (TP), potassium (TK), available (AN), (AP), (AK), sand, silt, clay) used layer index (SQI). results showed that Province generally above moderate level, nutrient contents increased West East among regions. minimum data set SQI (SQI-MDS) layers 0.22–0.98 (0.46) 0.23–0.93 (0.55), respectively. suitable ranges MDS parameters for reasonable as follows: SOM ≥ 34.5 g kg−1, 31.5% ≤ sand 53.5%, AP 32.1 mg TK 15.18 kg−1; 31.3% 51.2%, TN 1.48 6.4 pH 7.1, AK 157.6 kg−1. summary, different ecological zones are varied. It necessary adjust thresholds combination with actual conditions establish a more accurate system quality.

Abstract. Drought poses increasing challenges to global food production. Knowledge about the influence of drought on crop development and role soil properties for severity is important in risk analysis mitigating impacts at landscape level.

As a case study, assessed winter wheat growth 13 fields belonging commercial farmers southern Sweden dry year (2018) with normal weather conditions (2021). To track growth, green leaf area index (GLAI) was estimated imagery using radiative transfer model.

C content only surface layer, while use stock 23% compared system without 0–20 cm layer. In topsoil under NT, stocks particulate (POM) mineral-associated (MAOM) were 100% 37% greater than CT, respectively. A CMI observed CT (18%), one (52%), two (72%) crops. These results highlight till’s positive impact health, further enhanced legume-based ecological intensification
