Results of physical-chemical examinations performed during the SOILMAP project. To understand soil management and to maintain soil quality, we need to know about the chemical aspects of the soil, such as: soil pH, Soil texture cation exchange capacity, organic matter

Presentation Transcript

The soil texture from the researched points, in the first 40 cm, is mediumclay loamy (soil sampling 1, 3, 5, 6, 8, 9, 10), medium loamy (soil sampling 2), loamy clay (soil sampling 4, 7) for the hungarian samples and medium clay loamy (soil sampling 1, 3, 5, 6, 7, 8, 9, 10), loamy clay (soil sampling 2) , silty clay (soil sampling 4) for the romanian samples.

Soil cm, is pH is probably the most commonly measured soil chemical property and is also one of the more informative.

  • Humus cm, is provides soil with a number of very important benefits:

  • It enhances a soil's ability to hold and store moisture.

  • It reduces the eluviationof soluble nutrients from the soil profile.

  • It is the primary source of carbon and nitrogen required by plants for their nutrition.

  • It improves soil structure which is necessary for plant growth.

Phosphorus (P) cm, is is essential for plant growth. It stimulates growth of young plants, giving them a good and vigorous start. Phosphorus management and nutrition has both economic and environmental implications.

To fulfill its many roles in plants, cm, is potassium K is absorbed in rather large quantities, even exceeding the amount of nitrogen

  • Total cm, is zinc content in soil is ranged between 40 ppm and 140ppm in Hungary, and between 30 ppm and 75 ppm in Romania.

  • Copper content in soils vary in a large domain, being ranged betwwen 20ppm and 130 ppm for Hungary, and respectively 71 ppm for Romania.

  • Highest manganese content was determined in Romanian soils, maximum value was 967 ppm.

  • Hungarian soils are richer in nickel, highest value being determined in Mako area, 50,1 ppm.

  • Soils from Hungary – Romania border area have a low cadmium content, non of the values exced maximum admitance levels.

  • Lead content of Romanian soils are relatively low (2 – 30 ppm), but in Hungary in Mako and Forest are, at depth of 0 -20 cm, lead content exceded admitance level of 50 ppm. In Ujszeged and Othalom this value is exceded at depth of 20 – 40 cm, perhaps because of lead levigation.

Conclusions cm, is

  • Considering all determined chemical indicators, we can conclude that the soils of the Hungary - Romania are quality soil, with pH from acid to slightly alkaline, medium humus content and well supplied with phosphorus and potassium.

  • To maintain quality in terms of soil chemistry, is required:

  • Enhance organic matter

  • Manage nutrients and pests efficiently

  • Prevent soil compaction

  • Diversify cropping systems
