Bu çalışmanın amacı, Çarşamba Ovasında yetiştirilen soya bitkisinin verim parametreleriyle (bitki boyu, bin tane ağırlığı ve verimi) toprakların bazı kimyasal özellikleri arasındaki korelasyon ilişkilerine dayanarak, bu özellikler arasında pedotransfer modellerin oluşturulması elde edilen ova topraklarında bitki veriminin tahmininde uygulanabilirliğinin belirlenmesidir. amaçla, ovanın çiftçiler...
Soil bulk density measurements are often required as an input parameter for models that predict soil processes. Nonparametric approaches are being used in various fields to estimate continuous variables. One type of the nonparametric lazy learning algorithms, a k-nearest neighbor (k-NN) algorithm was introduced and tested to estimate soil bulk density from other soil properties, including soil ...

Direct measurement of soil hydraulic characteristics is costly and time-consuming. Also, the method is partly unreliable due to soil heterogeneity and laboratory errors. Instead, soil hydraulic characteristics can be predicted using readily available data such as soil texture and bulk density using pedotransfer functions (PTFs). Artificial neural networks (ANNs) and statistical regression are t...
Accurate saturated hydraulic conductivity (Ksat) predictions are critical for precise water flow estimations. Pedotransfer functions (PTFs) have been used to estimate Ksat based on soil structural and textural properties. However, PTF accuracy must be validated with observed values improve confidence in model predictions. A study was conducted the seasonal wetlands of a representative mixed lan...
