Why is Soil Analysis Performed? The Secret of Yield Increase in Organic Farming
Soil Analysis and Why is it Critically Important?
Soil analysis is the cornerstone of success in agricultural production. Through this analysis, soil nutrient content, pH value, and organic matter amount are determined. Additionally, necessary conditions for healthy plant development are identified.
Performing soil analysis in modern agriculture provides significant advantages both economically and environmentally. This analysis is particularly indispensable in organic farming practices.
Primary Objectives of Soil Analysis
Determining Nutrient Element Deficiencies
The primary purpose of soil analysis is to understand the status of nutrients that plants need. Therefore, macro elements (nitrogen, phosphorus, potassium) and micro elements (iron, zinc, manganese) are measured.
As a result, which nutrients are deficient becomes clearly evident. Thus, unnecessary fertilizer use is prevented and cost savings are achieved.
pH Level Control
Soil pH directly affects the availability of nutrients to plants. Because each plant species shows optimal development in different pH ranges.
Aluminum toxicity risk exists in acidic soils. In contrast, iron and zinc deficiency occurs in alkaline soils. Therefore, pH control is vitally important.
Role of Soil Analysis in Organic Farming
Organic Matter Management
In organic farming, organic matter is the heart of the system. Organic matter amount is determined through soil analysis and compost needs are calculated.
Organic matter also increases water holding capacity. Additionally, it improves soil structure and supports microorganism activity.
Sustainable Fertilizer Planning
In organic farming where chemical fertilizer use is limited, natural nutrient sources are critically important. Therefore, existing reserves are identified through soil analysis.
Subsequently, green manure applications are planned and organic fertilizer amounts are determined. Thus, both yield increase is achieved and the environment is protected.
How is Soil Sampling Performed?
Proper Timing
The most suitable period for soil sampling is autumn. Because plant nutrient uptake is at minimum level during this period. Additionally, the real soil condition is seen more clearly.
Spring period is also suitable for pre-planting planning. However, the effect of winter precipitation should be considered.
Sampling Techniques
Zigzag method is used in homogeneous areas. Samples are taken from 15-20 different points for one hectare area. Separate sampling is done for different soil types.
Sampling depth varies according to plant type. 0-20 cm depth is ideal for field crops, 0-30 cm for fruit trees.
Evaluation of Analysis Results
Nutrient Element Levels
Analysis results are generally evaluated in five categories: very low, low, sufficient, high, and very high. Each category requires different action plans.
Very low levels require immediate intervention. High levels indicate that fertilizer application is unnecessary.
Practical Application Recommendations
pH value should be between 6.0-7.0. Organic matter ratio should be kept above 2%. Salinity level should be kept under control.
When these values are achieved, plant development is optimized. At the same time, disease resistance increases and yield rises.
Economic Benefits and Cost Analysis
Saving Opportunities
Farmers who perform regular soil analysis achieve 10-30% fertilizer savings. Additionally, they obtain 15-25% yield increase.
Unnecessary fertilizer use is prevented and environmental pollution is reduced. Thus, both economic and ecological gains are achieved.
Return on Investment
Soil analysis cost varies between 50-300 TL. However, the savings and yield increase it provides covers this cost in a short time.
In the long term, soil health is preserved and sustainable production is ensured. As a result, farmer profitability increases.
Conclusion and Recommendations
Soil analysis is indispensable for the success of organic farming. Through regular analyses, soil health is preserved and yield is optimized.
For successful results, perform analysis at least once a year. Get professional support and meticulously apply recommendations. Thus, both your soil and your pocket will thank you.
