O Sistema de Plantio Direto foi introduzido no Brasil no final da década de 1960, contudo, esse já vinha sendo empregado nos Estados Unidos desde 1950, demonstrando grandes benefícios. O objetivo do trabalho foi abordar o plantio direto no Brasil, expondo suas características e seus benefícios para a conservação do solo. É imprescindível o conhecimento técnico para obter sucesso na implantação deste sistema, e se destacam cuidados com o solo, como identificação do tipo de solo, eliminação de camadas compactadas, nivelamento, correção de acidez, entre outros. A utilização de plantas de cobertura merece atenção, pois proporciona proteção das camadas superiores do solo, evitando a erosão. Dessa forma, devem ser priorizadas as plantas de rápido desenvolvimento, visto que quanto mais rápido o desenvolvimento da espécie, mais rápido serão proporcionados os benefícios físicos ao solo. Além disso, trata-se de uma prática viável de se empregar em áreas de cultivo agrícola. Em conjunto com a adoção do método do plantio direto se pode empregar a prática de rotação de cultura, que também se mostra eficiente no processo de conservação dos recursos naturais, com destaque para o solo. Conclui-se que desde sua implantação, o sistema de plantio direto vem trazendo inúmeras vantagens para a conservação do solo, melhorando a qualidade, aumentando a rentabilidade das áreas de exploração agrícola. Palavras-chave: Agricultura Conservacionista.

The objective of this work was to address no - tillage in Brazil, exposing its characteristics and its benefits to soil conservation. It is essential the technical knowledge to be successful in the implementation of this system, among them stand out soil care, such as identification of soil type, elimination of compacted layers, leveling, acidity correction, among others. The use of cover plants deserves attention, as it provides protection of the soil upper layers, avoiding erosion. Therefore, fast-growing plants should be prioritized, since the faster the development of the species, the faster the physical benefits will be provided to the soil. In addition, it is a viable practice to employ in agricultural areas. In conjunction with the adoption of the no-tillage method, it is possible to use the crop rotation practice, which is also efficient in the conservation process of natural resources, especially soil. It is concluded that since its implementation, the no-tillage system has brought innumerable advantages to soil conservation, improving its quality, increasing the farm areas profitability. Keywords: Conservationist Agriculture.

Abstract In response to soil and environmental problems in the Citarum river of West Java, the upper Citarum watershed has focused on government policy intervention. The policy framework primarily focuses on encouraging soil conservation practices and promoting an environmentally friendly farming system. However, most empirical research on this subject failed to acknowledge that the conservation practices varied with the stage of rural transformation. This paper aims to assess rural transformation in the upper Citarum watershed and its relation to soil conservation practices. We use Indogreen Farm Household Survey (IFHS) data collected in 2019 from Bandung and West Bandung districts, covering six sub-watersheds, 22 villages, and 500 farm households. The sub-watersheds are divided into two groups based on the degree of rural transformation. Descriptive analysis using graphs and charts presented the data. The results show that the more dominant non-agriculture job characterizes household employment and income structure in the faster regions. Furthermore, farmers in these regions mostly choose higher-value commodities compared to the slower area. Finally, soil conservation practice is more intensive in the faster region in response to more intensive land utilization. The research implies that agricultural development programs, in particular extension services, should put this issue in perspective.

Soil Conservation Measures

<p>Land degradation by soil erosion, gullying, landslides and reservoir sedimentation is a major environmental threat in the Barlad Plateau of Romania. This paper reviews both land degradation and the development of soil conservation measures in a representative 32,908 ha catchment. Previous studies focused on larger regional areas and provided insufficient detailed information about land degradation and land improvements. Results estimated the mean value of soil loses at 22.7 t ha-1 y-1 based mostly on the USLE. Gully erosion is very limited in extent (covering 3% of the catchment area), but has considerable impacts in terms of sediment production and triggering or reactivating landslides. The 1:5,000 scale landslide distribution map shows that 56% of Racova Catchment is covered by landslides, in any shape or age. Most of them are shallow seated and inactive landslides. Traditional agriculture in the Barlad Plateau focused on ‘up-and-down slope’ farming on small plots. Soil conservation measures were actively undertaken over a 20-year period (1970-1989). However, more recent legislation (No. 18/1991 Agricultural Real Estate Act) includes two provisions that discourage maintaining and extending soil conservation practises. Hence, the former contour farming system has been abandoned in favour of the traditional, degradational farming methods. The mean annual sedimentation rate in reservoirs is moderate at 2.7 cm y-1 in the upper Racova Catchment and almost double that rate in Puscasi Reservoir at the catchment outlet. Consequently, land degradation remains a serious problem in the study area and effective soil conservation is urgently needed.</p>

Soil Depletion

This paper studies soil depletion incentives in a dynamic economic model under two different sources of revenue uncertainty (output and price risk). The focus is on the long-term effects of risk-averse preferences when farming decisions have implications for both expected short-run production and natural topsoil fertility. The analysis shows that the risk properties of the stock variable are crucial for the results arrived. The presence of risk preferences is found to improve soil conservation incentives in a low-input farming system, independent of the source of revenue risk considered. The only case for which soil conservation incentives are weakened is for high-input farming systems under price uncertainty.JEL classification: Q12, Q20, D81

Soil Conservation Measures

Land degradation by soil erosion, gullying and landslides and reservoir sedimentation is a major environmental threat in the Moldavian Plateau of eastern Romania. The widespread development of these processes in the last two centuries was favored mainly by traditional agriculture focused on ‘up-and-down slope’ farming on small plots. However, soil conservation measures were actively undertaken between 1970 and 1989. More recent legislation (No. 18/1991 Agricultural Real Estate Act) includes two provisions that discourage maintaining and extending soil conservation practices. Hence, the former contour farming system has been abandoned in favor of the traditional, inadequate farming methods. Thus, this paper reviews the impact of land degradation and soil conservation measures in a representative 32,908 ha catchment located in the Central Moldavian Plateau. Based on field measurements, the results show that the estimated mean long-term (1973–2017) sedimentation rate reaches 4.7 cm y−1 in the Puscasi Reservoir at the catchment outlet, resulting in an associated sediment delivery ratio of 0.28. The initial area of the Puscasi Reservoir at normal retention level has decreased by 32% and the water storage capacity has decreased by 39%. Consequently, land degradation remains a serious problem in the study area and effective soil conservation is urgently needed.
