Abstract

Recently, a lot
of progress have been obtain towards progress on the quality and quantity in
agriculture. The advances and development in agriculture depend on
mechanisation and the development on the soil characteristic which also help to
increase the product efficiency. This study aims to
determine some Turkish low rank coal
samples for applications in the agricultural sector and assesses the
suitability of a certain coal either as soil conditioner or as raw material for
manufacturing organic fertilizers. They
improve the soil structure and improve physical properties of soil by
increasing the exchange capacity and buffening qualities, promoting the
chelation of many elements and making these available to plants. Humic
substances can ameliorate negative soil properties; improve the plant growth
and nutrients uptake. Twenty-six samples of subbituminous coal obtained from several Turkish
coal deposits such as Arguvan,
Çayırlı, Artova and Zile, Kangal-Gemerek-Divriği were studied. When optimum parameters were used, the most promising samples for utilization are the coal
samples from Arguvan, Artova
and Zile, since they yielded high HA contents (≥30 wt). Although the Artova and Arguvan samples display high HA contents, they are also rich
in S and release Fe, which might be threatening for the plants.
