The Use of Biochar and Compost Mixtures as Potential Organic Fertilizers

Abstract

Organic wastes have been used in agriculture many years ago, due to its capacity to improve soil quality. The manure was used before the occurrence of chemical fertilizers and treated / untreated sewage sludge, started to be used as a fertilizer a few years ago. The aim of the study is to evaluate the organic matter, organic carbon, organic content and soil composition, after application in greenhouse conditions, of mixtures made from sewage sludge biochar and cattle manure compost. The biochar and compost used in different concentrations, at 5 t/ha and 30 t/ha, application rates, in greenhouse conditions, for a period of 90 days, improved organic matter, organic carbon and organic content from the soil used in experiment. The sewage sludge biochar and the cattle manure compost had similar effects on the parameters determined in the study. Organic and inorganic soil components, identified by the ATR-FTIR method, have not been modified by application of sewage sludge biochar and cattle manure compost.

Influence of Fertilizers on Soils Used for Oleaginous Crop

“…According to the data presented in the Code of good agricultural practices, 36.5 kg of nitrogen, 17.5 kg of phosphorus and 50 kg of potassium, active substances are required to produce a ton of oleaginous crop seeds and strains [3,4,24,[25][26][27][28][29][30][31][32][33][34][35][36][37].…”

Utilization of Ozone and Composite Materials in the Seed Treatment to Stimulate the Germination and Growth of Agricultural Crops

“…Lately, an alternative in agriculture to stimulate the processes of agricultural development and harvesting of pure organic products is the use of physico-chemical methods. It has been established that ozone has unique antibacterial properties, ecological and safe for the environment, influences the microflora and increases the yield of plants [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35].…”

Influence of Soil Fertilization Systems on Chemical Properties of the Soil

“…An important consequence is the accumulation in large quantities of the residual organic materials of solid, liquid and semi-liquid consistency. Normally these residues, with the value of organic fertilizers, are used to fertilize agricultural land [12,16,[28][29][30][31][32][33][34][35][36][37][38].The purpose of this research has been to determine the in2fluence of soil fertilizations systems on the chemical properties (magnesium, aluminium, potassium, calcium, iron and chlorine).…”
