Co-application of compost or inorganic NPK fertilizer with biochar influences soil quality,grain yield and net income of rice

Most agricultural soils in sub-Saharan Africa are degraded,compromising the grain yield of rice and farmers return on investment.A 3-year field study was undertaken to explore the effect of the application of compost or inorganic NPK fertilizer applied alone or in combination with biochar on soil quality,grain yield of rice and net income.The five treatments were laid out using a randomized complete block design with four replications.The treatments were applied to supply approximately 75 kg N ha–1.The best fertilizer input was compost+biochar which resulted in the greatest improvement in soil physico-chemical properties by reducing bulk density and increasing porosity and moisture retention,organic matter content,percent nitrogen,available phosphorus and cation exchange capacity.Apart from treatment with inorganic fertilizer alone,treated soils showed a decrease in pH.Bacterial and fungal counts and basal respiration decreased in soils in the following order:compost+biochar>compost only>inorganic NPK fertilizer+biochar>inorganic NPK fertilizer>control.The increase in pooled grain yield and net income in response to treatment followed the order:compost+biochar>NPK+biochar>NPK>compost>control.The findings suggest that the use of compost or NPK alone might improve soil quality and increase grain yield and net income,but it is greatly recommended to co-apply these fertilisers with biochar.

Territorial Inequality of Net Income per Peasant in Shandong Province and Its Mechanism

Income inequality among farmers living in different regions was an important form of territorial inequalities. Studying the territorial inequality of the net income per peasant was an emphasis of this paper, and Shandong Province was pointed as the case study region. By the help of logistic regression, it could be found that the special distribution of the net income per peasant in Shandong Province was affected by three factors： distance to No.308 National Highway, distance to the coastline in the east of Shandong Province, and urbanization rates. Based on the decomposition of Gini index, the net income per peasant was divided into four parts, and it was found that the income from family business and salary were the two major sources of income. As to the mechanism for income inequality, it was proved that urbanization was still the key factor. In order to reduce income inequality, the local governments should promote urbanization through improving road networks, such as building highways, which could connect rural areas with the major nodes such as big cities and the port cities in the east.

Dynamic Changes in Per Capita Net Income of Rural Residents in Nyingchi City of Tibet

Through an in-depth analysis of the per capita net income of rural residents in Nyingchi City,it was known that the per capita net income of rural residents in Nyingchi City was increasing at high speed in recent 10 years. However,the wage income,household operating income,and agricultural income gap constitute the major factors influencing the gap of the per capita net income of rural residents in Nyingchi City. Finally,it came up with recommendations including promoting the reasonable flow of labor to the secondary and tertiary industries,increasing the wage income and transfer income of rural residents,accelerating the construction of small towns in rural areas,promoting the development of rural cooperatives,implementing the strategy of " benefiting farmers and strengthening tourism",promoting integration of agriculture and eco-tourism,promoting the development of modern agriculture,and expanding diversified production income of farmers.

Quantitative Analysis of Impact of Education on Improving Farmers′ Net Income and Yield Per Capita

In this paper, we analyze the relation between farmers′ schooling and their net income and yield per capita by systemic and scientific method, concluding that improving farmers′ educational level may increase their net income.

Research on the Development of Economy and Farmers' Income Growth in Heilongjiang Province

Nowadays, increasing farmers＇ income is not only related to the development of rural economy, the improvement of farmers＇ lives and countryside stability but also related to the overall situation of economy and social development. Heilongjiang is a big agricultural province, however, the increase of farmers＇ per capital net income is rather slow in the last few years. On the basis of Lewis dual economic structure theory and our province＇s actual situation, the paper proposed the concrete countermeasures to increase farmers＇ income, so as to promote the development of economy.

Income Growth of Peasants Based on Grey Theory

Taking Jiangsu Province for example and using the relevant data in Jiangsu Statistical Yearbook and Statistical Communique of Jiangsu Province on National Economic and Social Development during 2002-2009,the thesis selects eight indexes including per capita net income of farmers,the fixed asset investment level in rural areas,average educational level,agricultural scientific and technological level,urbanization level,industrialization level,average consumption level per rural residents and per capita GDP and adopts the theory of grey correlation to analyze the factors influencing the peasants' net income.As shown in the result,the effect on the peasants' net income gives the following subsequence from great to little:average consumption level per capita of rural residents,urbanization level,average educational level,industrialization level,per capita GDP,number of scientific and technical personnel and fixed asset investment level in rural areas,that is,r06>r04>r02>r05>r07>r03>r01.Then combining with the practical conditions,the thesis makes a detailed analysis of each factor influencing the peasant's income growth and proposes corresponding measures in order to improve the peasants' income.
