Facing up to the paradigm of ecological intensification in agronomy: Revisiting methods, concepts and knowledge

Conservation agriculture has been proposed as a widely adapted set of management principles that can assure more sustainable agricultural production. Conservation agriculture removes the emphasis from the tillage component alone and addresses a more enhanced concept of the complete agricultural system. Applying conservation agriculture essentially means altering literally generations of traditional farming practices and implement use. Within the framework of agricultural production, high soil quality equates to the ability of the soil to maintain a high productivity without significant soil or environmental degradation. A comparative soil quality evaluation is one in which the performance of the system is determined in relation to alternatives. Inconsistent effects of a reduction in tillage on the variation in total porosity with depth may be related to differences in traffic on different sites, or on soil quality at the time tillage was reduced or stopped.

Conservation agriculture, improving soil quality for sustainable production systems?

Vineyards represent one of the most erosion-prone types of cultivated land. Because of this, cultivation practices are very important in reducing the soil erosion risk in vineyard regions. The aim of this paper was to assess the impact of various management practices on soil loss in vineyards. Effects of tillage, hoeing, rotavating and grass cover were evaluated in small vineyards located in southwestern Slovakia in the Vrable viticultural district. Erosion and deposition rates were estimated using the levelling method. This method is based on an evaluation of variability of the soil surface against vineyard poles measured between the year of pole insertion and the year of measurement. On the basis of the measured data, a WATEM/SEDEM distributed soil erosion model was calibrated, and the total soil loss from the vineyards under different management conditions was estimated. The model shows rather good performance in modelling soil erosion, but at the same time, it shows lower reliability in modelling soil deposition. Downslope tilled vineyards were the most eroded; the erosion in rotavated vineyards is somewhat reduced. The most protective tillage system is hoeing. Considerably lower soil loss was estimated with the use of vegetation cover between vine rows, which is in accordance with agro-environmental schemes supporting use of grass cover as an erosion prevention measure in vineyards.

The work focuses on analyzing the richness of weeds in family farms with horticultural production, the areas where we can preserve this vegetable resource, and from comparative studies, inquiring into the potentiality of weeds to enhance agroecological production systems. The research was done in two conventionally managed and two agroecological farms. The richness of weeds in three selected sectors was registered in relation to the disposition on the field: cultivated lot, edge of cultivated lot and boundary of the whole of registered area. Differences between farms with different managements were more evident in the number of species rather than the number of families. The differences were noticeable in the cultivated lot. Higher species richness was observed in the agroecological farms. The weeds, it is an important element to bearing in mind for the comprehension of the transition process.
