The structural characteristics and the factors affecting the soil analysis decisions of the farmers in Edirne and Tekirdağ provinces were determined in this study. The factors affective on the soil analysis decisions of the farmers were analyzed by using logistic regression analysis and artificial neural networks and the comparison of the methods was done. In each province, 3 laboratories which had the most sample acceptance number for soil analysis were selected. The surveys were conducted with total of 60 farmers who referred to the laboratories and utilized from soil analysis subsidies and 40 farmers who did not utilize from soil analysis subsidies and had the similar characteristics with the farmers who utilized from soil analysis subsidies in each province and total of 200 farmers participated in the survey in 2019. The most significant factors on soil analysis decisions of the farmers were determined as total land size, age, agricultural experience, experience on taking soil sample, family size, education period and the activity type in each two methods. Total accurate classification ratio was found as 77% in logistic regression analysis and 80.67% in artificial neural network analysis. It was determined that the classification percentages obtained by two methods were pretty close to each other. The farmers who had low yield and low qualified crop due to not having soil analysis should be informed and necessary publication studies should be done.

Insufficient fertilizing does not increase yields, not only because it is not economical if applied excessively but also it degrades physical and chemical structures of soil and pollutes environment. It is possible to minimize these negative effects by fertilizing based on soil analysis. The purpose of this study is to determine where farmers from Ankara province of Turkey stand on fertilizers; their attitudes, ideas, thoughts about having their soils analysed. The data were collected through face to face interviews with 61 farmers in the research area. The sample size was determined by using " Simple Random Sampling ". The questionnaire was designed to specify farm-ers' concerns over having soil analysis done and their implementations. Some statistical tests with SPSS were performed to distinguish differences between farmers' choices regarding soil analysis. According to the survey results, 80.3% of the farmers have their soils analysed at least once up to now and...

Judicious application of chemical fertilizers by farmers in crops is very essential to achieve maximum production and maximum profit. Soil testing is a comprehensive soil fertility evaluation programme, which helps the farmer’s to apply chemical fertilizers in a judicious way. The farmers should be able to know the exact quantity of nutrient to be applied for a particular crop based on soil test analysis. The majority of farmers have knowledge about soil testing practices. Majority of respondents were using the knowledge gained from scientists working in Krishi Vigyan Kendra and the experts of State Department. of Agriculture. Most of the respondents were in disagreement with the statements and mostly adaptors possessed unfavourable attitude towards soil testing practices. Majority of farmers agreed with the statement "Soil testing is necessary for better crop production". Efforts must be made by KVK and the Ministry of Agriculture. to encourage the farmers in adoption of ...

Soil analysis is used to determine the needs of the soil fertilizer. A good fertilization, determination of the amount and the type of fertilizer needed by the plant at the right time according to the technique of this fertilizer is to be buried. One of the inputs that affect most of the increase in efficiency at agricultural production is manure. In order to increase the incomes of farmers and crop production due to increased efficiency in mind, to use the correct type and amount of fertilizer is inevitable. A significant portion of the material to be used in research, in Konya province made from wheat breeding survey of the farms the data to be obtained. By going to the company by way of interviews with operators in the sample data of 2013 and 2014 production period is finished the questionnaire. Enterprises grow wheat for research; as soil analysis and make those checks is determined in two sets. The survey will be administered enterprises are determined by simple random sampling method (SRS). In the process of data analysis, SPSS or Eviews software package is used. Introductıon The content of soil and plant nutrients yield ability to increase the agricultural production is important. Plants need the plant nutrients in the soil to grow. If there araen't enough nutrients in the soil for the cultivation of plants, the appropriate type and amount of fertilizer must be given to close the gap. If the soil is deprived of essential nutrients and fertilizer contribution yet, yield losses are seen after a while. In this regard, soil analysis is used in determining the fertilizer required by the soil. A good fertilization, determining the amount and the type of fertilizer the plant needs at the right time according to the technique of this fertilizer is to be buried. The type and amount of fertilizer required for soil laboratories specializing in various soil samples taken from a certain land is determined. In favor of soil analysis, food ingredients required by the soil can be determined correctly. One of the most affecting inputs increasing the yield in agricultural production is fertilizer. The share of fertilizers in productivity growth varies depending on various conditions. Fertilizer prices in the available resources to farmers in those with significant increases are required to use the most efficient and shipped to adopt new technologies. Otherwise, while fertilizer costs and the type and amount of fertilizer that farmers use unconsciously are increased, the efficiency to be obtained will decrease. In this context, soil analysis with minimal impact from rising costs and the efficiency of determining the appropriate type and amount of fertilizer will be provided in a significant increase in earnings. It is important in terms of proper fertilization techniques to conserve natural resources. Turkey is a country with a growing population structure and that Turkey's annual growth rate of population for 2013-2014 is ‰13.3 (Turkstat, 2015). This is to increase the agricultural production for an adequate and balanced nutrition of the population, it is necessary to

The recognition of the influence of management practices on soil physical and chemical conditions is substantial for sustainable agriculture. For this reason, this study was developed for the purpose of evaluating the behavior of soil attributes under different uses in the region of Humaitá, AM, using multivariate statistical methods. The study was developed in 8 rural properties producing bananas, grassland, maize, coffee, cassava, vegetables, agroforestry system and a forest fragment. Samples of soils with preserved structure in the 0.0-0.10 and 0.10-0.20 m layers were randomly collected in 5 small trenches per area, totaling 32 samples in the management systems, to determine the physical and chemical attributes. The data were then submitted to univariate and multivariate statistical analysis. Exploratory data analysis (principal components and dendrogram) and frequency of environmental covariates was efficient in distinguishing production environments, so multivariate classification based on physical and chemical attributes of the soil can help in the proper planning of land use. The analysis of the principal components indicates that the BD presents direct dependence with the SPR, signaling the use of the soil with grassland the only one in the process of compaction. Soil acidity is the main limiting factor for crop development, requiring the adoption of pH corrective practices with improvements in nutrient supply. The conversion of the forest to grassland maintained the structural characteristics of the soil, while the other uses increased improvements in physical quality and soil fertility.

Plant growth requires nutrients and their functions in plants cannot be replaced by other elements so that if there are not enough nutrients in the soil, plants cannot grow normally. The nutrient content in the soil and the ability of the soil to provide nutrients for plant growth is different. So that the type of fertilizer and the amount of fertilizer given to each type of soil will be different and it depends on the type of plant being cultivated. To determine the requirements of fertilizers and the types of fertilizers required for each type of soil, need some research about the evaluation study of soil fertility. The research was conducted in Aceh Besar with located between 5¼ 2 ‘-5¼ 8’ N and 95¼ 80 ‘-95¼ 88’E. Assessment of soil fertility status based on the criteria of several soil chemical properties, CEC (cation exchange capacity), alkaline saturation, C-Organic, P2O5 (HCL, 25%) mg / 100g, and K2O (HCL, 25%) mg / 100g. The analysis results obtained from 11 sample points sho...

Soil information is a critical element in any agricultural venture. It often provides the missing link between assumptions and actuality in agricultural and non agricultural land use. A field study was carried out to assess the effects of poor application of soil information and the present level of soil information and utilization among small scale horticultural crop farmers in Ib were selected from two citrus orchards planted on suitable and marginally suitable soils based on available soil survey information which was monitored over two seasons, while structured questionnaires were administered to get empirical data on land use by the farmers. was significantly different (P <0.05) with loss of some trees after 15 years of establishment of the orchard on marginally suitable soils. Mean yiel suitable plots respectively. None of the respondents sought professional advice on land use or have knowledge of previous land use type while the farms were not surveyed before use. 56.27% of t do not carry out soil test while less than 10% of the farmers apply fertilizers suggesting nutrient mining with an average land use period of 14years. The findings of this work show that soil information is not adequately utilized among horticul farmers on the need for accurate soil information and application for enhanced horticultural crop production. INTRODUCTION The performance of any horticultural venture depends to a very large extent on the amount of soil information that is available and applied by the farmers. Ogunkunle (1989) citing Babalola (1974) stated that soils in the same series can show difference in crop yield. Application of soil information is a necessity for horticultural crop performance as this helps to improve existing knowledge in the production area and invariably increase crop production if it is effectively utilized in managing crop productio soil survey or soil test can be used for land use planning. (Okafor, 2008; Ashaye, 1987).
