Abstract
Half of the orchards of Hungary are in Szatmár-Bereg County. The county is in North-east Hungary. The total area of this micro region (5936 km²) covers 6.6% of the country’s overall territory (90 030 km2). The most common soil types of the planted areas in Szatmár and Bereg region are acidic meadow (WRB Vertisol) and acidic sediment (WRB Fluvisol) soils, while sandy (WRB Arenosol) soils dominate the neighboring area (Nyírség). In this study several chemical parameters were investigated, including ammonium lactate (AL) soluble phosphorus and potassium content of soils of fruit plantations. Ammonium soluble phosphorus and potassium contents of soils are represent determining the current amount of phosphorus and potassium available to plants in the soil solution. We established nutrient deficiency caused by acidification of soils and the need for rational fertilization of the soils in the region. Results of soil analysis can contribute to sustainable soil and land use by considering soil and plant nutrient requirements.
Highlights
Diversity of Hungarian soils has been shaped by the rocks of the Carpathian Basin, climatic conditions, configuration of the terrain, biological factors, consequences of human activity, and effects of time (Michéli, 2016.) Soil is a renewable natural resource with finite renewable ability
Fifty randomly selected zones from Szatmár and Bereg Counties revealed in a representative manner the actual condition of soils in these areas
According to the SIM database, phosphorus supply of soils are the followings: 42% of soils contain below 100 ppm P, 26% have 100-200 ppm P content, 21% of soils fall in the phosphorus range between 200-400 ppm, and only a small percentage of soils are abundant in phosphorus
Summary
Diversity of Hungarian soils has been shaped by the rocks of the Carpathian Basin, climatic conditions, configuration of the terrain, biological factors, consequences of human activity, and effects of time (Michéli, 2016.) Soil is a renewable natural resource with finite renewable ability. Anthropogenic effects have deteriorated the multifunctional nature and quality of soils, causing a need to protect the multifaceted functions of soils. These principles represent part of the foundations of sustainable development (KVVM, 2017). Inland excess water (IEW) is a form of surplus surface water, frequently regarded as a specific flood type. It occurs most often in local depressions of large flat areas, irrespective of river floods and the surface water networks. Pasztor and co-workers investigated parameters that quantize the effects of soil geology, groundwater, land use, and hydrometeorology on the formulation of e!7 / e13 e!8 / e13
