ABSTRACT: Sugarcane covers 10.6 Mha of Brazilian agricultural land (13 % all cropland), mainly in the south-central region. In tropical climate conditions, physiological characteristics sugarcane allow a wide range management systems with contrasting soil erosion outcomes. Models can assess these differences and Universal Soil Loss Equation (USLE) based models are most frequently used. The cove...

As one of the key tools for regulating human-ecosystem relations, environmental conservation policies can promote ecological rehabilitation across a variety of spatiotemporal scales. However, quantifying the ecological effects of such policies at the regional level is difficult. A case study was conducted at the regional level in the ecologically vulnerable region of the Loess Plateau, China, t...

The assessment of sustainability in cropping system is an important issue for natural resources management and environmental protection. Incorporating the geographical information system (GIS) and remote sensing (RS) technologies, an initial idea of the crop sustainability assessing system was thus proposed, based on ecosystem services value (ESV) assessing criterions. The system is basically c...

Purpose Excess phosphorus from fertilizer application and mobilised soil phosphorus from erosion are partially lost to the aquatic environment where they might cause eutrophication. Phosphorus emissions vary spatially and it is the goal of this study to broaden the scope of the existing inventory to the global scale and to increase the spatial resolution by accounting for relevant environmental...

Rainfall erosivity factor (R-factor) is one of the Universal Soil Loss Equation (USLE) input parameters that account for impacts rainfall intensity in estimating soil loss. Although many studies have calculated R-factor using various empirical methods or USLE method, these are time-consuming and require specialized knowledge user. The purpose this study to develop machine learning models predic...

The greatest obstacle to soil erosion modelling at larger spatial scales is the lack of data on soil characteristics. One key parameter for modelling soil erosion is the soil erodibility, expressed as the K-factor in the widely used soil erosion model, the Universal Soil Loss Equation (USLE) and its revised version (RUSLE). The K-factor, which expresses the susceptibility of a soil to erode, is...

Waduk Cengklik adalah waduk yang terletak di Desa Ngargorejo, Kecamatan Ngemplak, Kabupaten Boyolali, Provinsi Jawa Tengah. sendiri memiliki fungsi utama sebagai pemasok air irigasi pada 3 kecamatan yaitu Sambi, dan Nogosari. Oleh karena setiap tahunnya cengklik mengalami penurunan tampungan menyebabkan kurangnya pasokan ke pertanian terutama saat musim kemarau. Hal ini disebabkan oleh besarnya...

The P-factor for support practice of the Universal Soil Loss Equation (USLE) accounts soil conservation measures and leads to a significant reduction in modelled loss. However, practical application, is most neglected factor overall due high effort determining or lack input data. This study provides new method automatic derivation main cultivation direction from seed rows tramlines on agricultu...

In the current study processes of soil deterioration over past five decades was evaluated. Land degradation risk, status, and rate were assessed in Kafr El-Sheikh Governorate, Egypt, 2016 using OLI ETM (2002) remote sensing data, data from 1961.A quantitative produced based on comparative approach integrated weighted sum, overlay, fuzzy model. The parameters used depth, texture, pH, EC, OM, SAR...
