Usually large numbers of measurements are required to describe spatial variability of soil resistance but GIS technology with interpolations methods make it possible to estimate data from unsampled locations. In this paper cone index (CI) measurements were made in two occasions in 2.88 ha fi eld in central Croatia to present soil condition. A commonly used tillage operation consists of ploughin...

INTRODUCTION Acid reaction and nutritional unbalances, mainly low level of plant available phosphorus (P) as well as unfavorable physical properties are limiting factor of soil fertility in Bosnia (Okiljević et al., 1997; Resulović and Čustović, 2002). It is estimated that about 25% of agricultural land of Bosnia and Herzegovina are pseudogley or similar soils (Marković and Supić, 2003). P as a...

This paper describes the findings of selenium measurement in three types of soil (semigley, pseudogley and hypogley) and in wheat grain cultivated in these types of soil in the vicinity of Koprivnica using hydrid atomic absorption spectrometry. The results showed relatively low selenium levels in all three types of soil (145-333 micrograms Se/kg dry weight) as well as the wheat grain (22-62 mic...

many farmers periodically use deep tillage operations to alleviate compaction in the soil profile caused by natural factors or machinery traffic. in 2012 and 2013, a study was initiated in the pannonian region of croatia to study the effects of no-tillage (nt), conventional tillage (ct) and deep tillage (dt) on soil compaction, measured by (bd), soil water content (swc), penetration resistance ...

Oat is widely grown in Western Serbia and compared to other cereal crops reputed be better suited for production under marginal environments, including low fertility soils cool wet climates. To determine the effect of cultivar growing seasons on yield components oats two varieties were examined during three years, field experiment secondary agricultural-chemical school "Dr Đorđe Radić" Kraljevo...
