NoItem These fractions are now considered an important indicator of soil quality Haynes,Ghani et al. Tolerance index TI has been regarded recently as the best reliable index for determining compounds toxic for plants in soil Audet and Charest, Labile, recalcitrant and inert organic matter in Mediterranean forest soils.
In recent years numerous attempts have been made all over the world to utilise kvalifativn ashes, also as a raw material for zeoliths manufacturing Bukhari et al.
If the index is lower than one, it indicates an inhibition of plant growth and sometimes their total dieback, equal to one shows no influence of pollution on yielding, while higher than 1 indicates a positive effect of pollution on plant growth and development.
Deforested land is used for growing and transporting drugs paths and airports are built in the forest through illegal deforestationurbanization of the population internal migration from villages to large agglomerations hndl their suburbs and expansion of infrastructure construction of roads, industrial zones, reservoirs of drinking water and others. The experiment was established in a warm maize-growing region in ej ‘ Since Costa Rica has lost 6.
Floodplain forest, dependent on water sufficiency, was partly preserved Vybral, Evaluation of physical attributes of a dystrophic red nitosol under no-tillage, conventional tillage and native forest systems.
The situation in El Salvador was affected by the cultivation of coffee. The effect of nitrogen and sulphur fertilization on yield and quality of kohlrabi Brassica oleracea, L. The Committee of the Environment of Nicaragua notes that the deforestation has had complete transformations on the landscape and environment making natural disasters more destructive. The causes of deforestation are also urbanization of landscapes urban sprawlinfrastructure building road network, water reservoirs, dams etc.
The situation is better in Belize, El Salvador and Panama. Effect of nitrogen and molybdenum levels on growth, yield and quality of cauliflower Brassica oleracea var.
The difference between the total Corg in cultivated soils and the determined contents of inert carbon is considered degradable organic carbon compounds Cdec. Total and labile soil organic matter in organic and conventional farming systems. Organic and conventional Weigel A. Global Biogeochemical Cycles, Another studied index which might be connected with cadmium uptake was zinc concentrations in maize Figure 1.

With respect to ability of long-term retention of soil water, both variants in site Oubnice are better having higher values of retention water capacity in comparison with site Tebsn. Journal of Plant Nutrition and Soil Science, In the absolute numbers, Costa Rica has twice as many forested areas in comparison with Honduras, which is the country with the highest percentage of forestation.
Ash admixture to cadmium polluted soil affected this metal binding in non-soluble forms, unavailable to plants. Application of subsequent cadmium doses 7. The highest cadmium uptake with maize yield was observed in the soil mixed with ash to which 15 mg Cd kg-1 soil d. Considering the permissible trace metal concentrations in top horizons of arable lands, it was noted that in the analysed fly ash these contents were clearly lower Table 1Regulation, Object 1, as the control contained only the soil, object 2 the soil with ash supplement, in objects doses of cadmium increasing from 3.
Therefore we can expect a favorable development in the future Anon. A qualitative assessment based on evidence of the presence of pollution sources diffuse or fixed Native flora and fauna disturbance. In the past, floodplains were used mainly for hunting Vaek, The influence of digestate and mineral fertilisers on yields and content of nitrates and ascorbic acid in the bulbs of kohlrabi.
During and the regulation of the middle course of Morava river up to Hodonn was finished, causing a significant increase in summer floods as quickly diverted water from higher parts of the basin in a straightened river basin could not be drained that quickly by the not yet regulated part of the river.
Some of the nutrients nitrogen stimulated straw decomposition; lacy phacelia utilised the rest for its growth. During the regulation of Morava and Dyje rivers a polder was developed in the floodplain forests which is to regulate the culmination flows on Dyje river so that flood waves on Morava and Dyje rivers do not meet Pavlk a kol.
This one is also richer in Nitrogen, which accelerates the decomposition process.
Vzkumn stav bramborsk Havlkv Brod s. In this work we studied SOM. Contents of labile fractions of the soil carbon and their degree of lability was studied in High Chuchelec in Kaplice Kol et al. The social function of ownership and expropriation of property for the common good was established there.
The rate of N was the same in treatments 23, i.
So, the varied SOM mixture could be clasified at least two large groups according to the different behaviour within mineralization and ion exchange. In case of higher amount of Calcium in soil the Potassium nutrition is improved Dickinson, Kvslitativn, The content of Cr, Cu and Ni assessed in the combustion ash was respectively over 6, 12 and fold higher in comparison with the soil content, whereas the concentrations of Zn, Pb and Cd in soil were respectively over 2.
Tolerance index calculated for maize in Authors own research Table 2 assumed values higher than 1 in objectswhere ash and cadmium were applied to the soil nan dose mg kg-1 soil d.

In addition, it will present a number of questions, risks and problems all connected with care for the kvaltiativn soil property – soil fertility. Rates were determined according to the content of mineral nitrogen before planting.
El Salvador worst issue is illegal logging Anon.
