Q10 - Agriculture: GeneralNávrat zpět

Fertilizer has brought great pressure to sustainable ecological environment. Research on the effect of price on fertilizer use as well as the substitution relationship of fertilizer and other input factors of agricultural production is of great importance for green, efficient, and intensive agricultural production in the world. This study first constructs translog cost functions and models of elasticity, then uses the factor input and price data from 2004 to 2016 to measure the price elasticity of fertilizer demand, and the elasticity of factor substitution in China's maize and cabbage production. The results suggest that: the price elasticity of fertilizer demand is in a low elasticity range; there is a compensation relationship between fertilizer and labour and a substitution relationship between fertilizer and machinery in China's maize production, while these relationships in China's cabbage production are opposite.

Subsidy to less favoured area (LFA) farms is central to rural development policy in the European Union. Here, three categories of LFA support are assessed: farm competitiveness measures, LFA measures, and agri-environment measures. These categories of measures are complementary to safeguarding land management and delivering ecosystem benefits. Based on historical data for the Czech Republic, this paper endeavours to illustrate potential methods for assessing the LFA subsidies. In sum, rigorous methods to evaluate LFA evidence are still at their very starting point, even as they are necessary in order to ascertain the Community's capability, alongside the local, regional, or national institutional capability. A positive trend has been identified with regard to  stabilizing the available rural development budget for the policy priority "Restoring, preserving and enhancing agroecosystems".
