Plastic Mulching

<p>Plastic mulching is a common farming practice in arid and semi-arid regions. Inappropriate disposal of plastic films can lead to the contamination of macroplastics (MaPs) and microplastics (MiPs) in the soil. To study the effects of plastic mulching on the contamination of soil with MaPs and MiPs and the role of farm management on this contamination, research was done on two farming systems in Northwest China, where plastic mulching is intensively used. Farming in Wutong Village (S1) is characterized by small plots and low-intensity machinery tillage while farming in Shihezi (S2) is characterized by large plots and high-intensity machinery tillage. Soils were sampled to a depth of 30 cm and analysed. The results showed that MaPs ranged from 30.3 kg·ha<sup>-1</sup> to 82.3 kg·ha<sup>-1</sup> in S1 and from 43.5 kg·ha<sup>-1</sup> to 148 kg·ha<sup>-1</sup> in S2. The main macroplastics  size categories were 2-10 cm<sup>2</sup> and 10-50 cm<sup>2</sup> in S1 and  < 2 cm<sup>2</sup> and 2-10 cm<sup>2</sup> in S2. In S1, we found that 6-8 years of continuous mulching practice resulted in the accumulation of more MaPs as compared to the use of intermittent mulching over the span of 30 years. For S2,  6 to 15 years of plastic mulching use led to MaPs accumulation in fields but from 15 to18 years, the MaPs number and content in soils dropped due to further fragmentation of the plastic and its dispersal into the environment. MiPs were mainly detected in fields with > 30 years of mulching use in S1 and discovered in all fields in S2, this indicated that  long-term cultivation and high-intensity machinery tillage could lead to more severe microplastic pollution. These results emphasized the impacts of  farm management on the accumulation and spread of MaPs and MiPs in the soil and regulations are needed to prevent further contamination of the soil.</p>

Inorganic And Organic

For the healthy growth and optimum yields of crops, organic and inorganic nutritional contents of soils are important factors. Region-wise surveys of soils for their mineral contents need to be conducted for suggesting the suitable types of crops to the farmers. It is also needed to suggest the farmers about the precautions to be taken for maintaining and improving the soil health of their lands. In this case study, 30 soil samples were selected from a village, Viramgaon, Tq. Khultabad, Dist. Aurangabad. These were critically evaluated for their nutritional contents. Based upon the analysis of the results, farmers of the region were given suggestion regarding quantities of inorganic and organic fertilizers, to be applied at appropriate times. Fertilizer applications of either organic or inorganic type, alone, hasn't been found to be sufcient. Hence, as an integrated approach for nutritional conservation of soils, this piece of study suggests combination of applications of both these types of fertilizers through a well scheduled plan.

Agriculture produces jointly market and non-market outputs, and their supply depends on the nature of production. The role of agriculture as an economic activity and its consequences are essential for the Lithuanian case study, as agricultural land covers more than a half of the Lithuanian land. The market does not consider the positive and negative externalities created in agroecosystems. Therefore, specific techniques such as stated preferences methods are used for evaluation of non-market outputs in agriculture. Works by foreign researchers provide a comprehensive analysis of the aspects of nontradable agricultural aspects, usually focusing on evaluation of the benefit or damage to society from agricultural activity. There is lack of an integrated evaluation of farming system outputs in view of the specifics and intensity of farming. The main aim of this paper is to present construction of the methodology for integration of evaluation of farming system outputs in Lithuania, with the main focus on non-market outputs, as the values of agricultural market outputs are clear and fully revealed in official statistics. The conventional and organic farming has been selected for the Lithuanian case study. For the both farming systems, the research covers crops (including both cereals and industrials crops) and livestock (including dairy and cattle) production. The choice experiment (CE) method was selected as appropriate for evaluation of non-market outputs of different farming systems in Lithuanian agriculture. The nested logit was selected for econometric modelling of the value of non-market agricultural outputs. Applying the constructed and checked methodology, consumers’ willingness to pay for agroecosystem public goods of different farming systems will be elicited during the main survey.

The institutional improvement as an important issue in the 2014-2019 Ministry of Agriculture Strategic Plan (Renstra). The development of the agricultural sector that relies on natural resource management needs institutional regulation to synergize efforts that support each other in achieving goals. Institutional improvements in clove agribusiness include; upstream to downstream agribusiness institutions involving farmers, government institutions and business actors. All institutions involved have a role in clove agribusiness activities, institutional farmers included in the group are farmers whose members are clove farmers in the management of cloves and gapoktan as a combination of farmer groups. This study describes the role of farmer group institutions in the agribusiness system including upstream subsystems, farming subsystems and downstream subsystems in clove management. This research uses a case study method with a qualitative descriptive approach. Data collection on the role of the Mayou City Farmer Group and the Aru Jaya farmer group association (Gapoktan) was obtained from the results of the interviews with the help of questionnaires or questionnaires. The role of farmer groups in clove management is presented in a descriptive qualitative analysis. The results showed that the existence of Mayou City farmer group institutions had not played an active role in any clove farming activities, this was due to the inactivity and lack of role and participation of members who preferred to focus on their respective farming systems. Thus the care and activeness of a member in the Mayou City Farmers Group are caused by the needs and interests to be achieved. Then the role of Aru Jaya Gapoktan did not work as it should because since its formation, only carried out the management of horticultural cultivation, especially vegetables and have never touched on how clove cultivation as a hereditary plant has been carried out by local communities.
