Numerical models of crop response to irrigation and weather forecasts with internet access should be fully utilized in modern management. In this respect, we developed a new numerical scheme optimize depth that maximizes net income over each interval. The applies volumetric water prices inspire farmers save water, it provides growers real-time estimates the growing season. To evaluate scheme, carried out field experiment for groundnut ( Arachis hypogaea L.) grown sandy Arid Land Research Center (ALRC), Tottori University, Japan. Two treatments were established compare proposed an automated system. Results showed although gave larger amount seasonal 28%, achieved 2.18 times owing 51% higher yield compared results accuracy rainfall forecast had little effect on outputs, where root mean square error (RMSE) between observed forecasted was 4.63 mm. By utilizing simulation information soil–plant–atmosphere system into would more cost-effective tool optimizing depths than systems.

This study explores agronomic management (AM) effects on soil parameters under diverse conditions. Investigating tillage practices (TP), nutrient (NM), crop rotation (CR), organic matter (OM), irrigation (IM), and mulching (MS), it aims to reveal impacts productivity, availability, microbial activity, overall health. Varied TP affect quality through compaction, porosity, erosion risk. Proper NM is vital for cycling, preventing imbalances acidification. CR disrupts pest cycles, reduces weed pressure, boosts recycling. OM enhances by influencing carbon, pH, fertility, water retention. Optimizing IM regulates content without inducing waterlogging. MS contributes content, retention, structure, temperature-moisture regulation, benefiting biota, aggregation, health agricultural productivity. The review emphasizes integrated nutrient, CR, management's positive impact fertility activity. Different variations production. Judicious implementation of these essential sustainable agriculture. synthesis identifies uncertainties proposes research directions optimizing productivity while ensuring environmental sustainability. Ongoing inquiry can guide a balanced approach between yields resilient stewardship future generations.

Abstract The use of soil moisture sensors for irrigation can help reduce water and energy consumption risks groundwater contamination, which are essential aspects pursuing sustainable development goals. However, increased adoption this technology is limited by calibration requirements, technical complexities, sensor costs. In work, a simplified method reducing the measurement error recently released low-cost (T-Higrow) presented. only requires measurements dry sample from target soil, inputted into simple correction formula to at higher levels. requirements proposed enough most labs or extension services. This was compared commonly used linear, polynomial, logarithmic regression models based on repeated bench-scale experiments within 0%–35% range in silt sandy loam soils silica sand. Uncorrected readings correlated well with ( r : 0.94–0.98), but significant overestimation (25%–60% error). showed comparable reduction across all types. All methods reduced down 2%–10% (0.02–0.1 cm 3 −3 ) maintained high correlations > 0.94), except correlation around 3%. Variability amongst generally low (Standard Deviation: 0.01–0.03) particularly ranges below 20%, also case sensor-to-sensor variability 0.01–0.03). Sensor evaluation works needed increase accessibility improved conservation.

The need to feed an increasing population while limiting the environmental impact of agriculture is currently one greatest challenges relating food chain. One key factors involved in doing this irrigation, which has a downstream that can be minimised if nutrient and water management are efficiently undertaken. objective study was determine irrigation improvements done at field scale modern irrigated areas reduce its return flow impact. conducted Noguera Ribagorçana River basin, NE Spain, where almost 6000 ha land were brought into from 2000 2009. We based our on quality dataset, measured four different sites along 29 km2 stretch river over period 20 years. Our results show increase nitrate (from 1.7 mg·L−1 10.5 mg·L−1) salt concentrations (electrical conductivity 297 675 µS·m−1) course compared most upstream monitoring site. That exclusively associated with flows newly area. highest found during non-irrigation season corresponds local rainy season. To impact, better required. Autumn leaching could lowered by reducing volume applied final weeks crop cycles order allow soil retain received rainfall. deal issue, we propose methodology moisture end In way, ecosystems located further would reduced yields productivity area maintained.

Soil-based irrigation and the partial substitution of chemical fertilizers with manure are promising practices to improve water nitrogen (N) use efficiency. We hypothesize that their combination would simultaneously benefit potato production, tuber quality profitability. A two-year experiment was conducted in semiarid northern China investigate combined effects three treatments [rainfed (W0), soil-based (W1), conventional (W2)] N [no (N0), (N1), 25% (N2)] on these indicators, perform a comprehensive evaluation correlation analysis. The results showed separately affected all indicators except vitamin C content. Compared W2, W1 significantly increased productivity by 12% efficiency (IWUE) 30% due 10% lower evapotranspiration 21% use. However, W2 negatively crude protein Conversely, this compensated N1 N2. There were slight differences between N2 for average across treatments, while under W1, leaf area index (LAI) recovery (REN) 18% 29.4%, respectively, over N1. Also, evaluations W1N2 performed best, highest yield, profit acceptable quality. This can be explained increase LAI, IWUE REN positive correlations yield net return. Consequently, had complementary synergistic

Abstract The cheap conductivity‐based sensors favoured by farmers for soil moisture monitoring remain largely ignored researchers because of their low accuracy, which results in high uncertainty regarding utility irrigators. In this work, conductivity measurements were compared with dielectric permittivity ranges relevant to different applications. showed that the captured variability well ( R 2 > 0.8) throughout full range tested (0%–35%), is consistent literature. Conductivity consistently distinguished dry from wet conditions p < 0.0001) and reflected lower 0.5) but not higher (>20%). This problematic important thresholds such as field capacity saturation are upper ranges. found lack any meaningful most applications except those distinguishing indicating lower‐range patterns, arid environments. gives some merit considering very cost if corrosion minimised. described evaluation approach suggested an example developers, labs extension services better communicate potential sensor utilities restrictions practitioners improve accessibility decision support technologies.
