Effects of Farmyard Manure and Inorganic Fertilizer Application on Soil Physico-Chemical Properties and Nutrient Balance in Rain-Fed Lowland Rice Ecosystem

Abstract

A field experiment was conducted to assess the effects of combined application of farm yard manure (FYM) and inorganic NP fertilizers on soil physico-chemical properties and nutrient balance in a rain-fed lowland rice production system in Fogera plain, northwestern Ethiopia. The study was carried out during the main cropping seasons of 2010 and 2011. Twenty-seven treatments comprising a factorial combination of three rates of FYM (0, 7.5, and 15 t·ha ) were tested. The experiments were laid out as a randomized complete block design with three replications. Bulk density, organic matter content, and available water holding capacity, total N, and available P of the soil were measured just after harvesting the rice crop. Results showed that application of 15 t·FYM·ha −1 significantly increased soil organic matter and available water holding capacity but decreased the soil bulk density, creating a good soil condition for enhanced growth of the rice crop. Application of 15 tFYM·ha −1 increased the level of soil total nitrogen from 0.203% to 0.349%. Combined application of 15 t·ha −1 ·FYM and 100 kg·P 2 O 5 ·ha −1 increased the available phosphorous from 11.9 ppm to 38.1 ppm. Positive balances of soil N and P resulted from combined application of FYM and inorganic N and P sources. Application of 15·t ha From the results of this experiment, it could be concluded that combined application of FYM and inorganic N and P fertilizers improved the chemical and physical properties, which may lead to enhanced and sustainable production of rice in the study area.

Effect of INM on Soil Carbon Pools, Soil Quality and Sustainability in Rice-Brown Sarson Cropping System of Kashmir Valley

“…The application of FYM increased Olsen-P because of its P content, and possibly by increasing retention of P in soil. These results were similar to the results reported by Ayoola and Titilola (2006), Walia et al, (2010), Moharana et al, (2012), Datt et al, (2013), Tadesse et al, (2013).…”

“…The bulk density of soil increased with depth 15 to 30 cm, varying from 1.18 to 1.30 g cm -3 in all the treatments. These results are similar to those reported by Walia et al, (2010), Nayak et al, (2012), Datt et al, (2013), Tadesse et al, (2013).…”

Effect of INM Modules and Different Cultural Practices on Properties of Silty Clay Loam Soil

“…This might be due to favorable soil condition by the application of organic manure which increased activity of microbes and thereby increase in available phosphorus status of soil. Similar findings were observed by Tadesse et al, (2013). It is clear from the data that the available K, S and Zn status in soil after harvest of rice crop varied due to the application of various combination of organic and inorganic source of nutrient.…”

Effects of Organic Residues on Soil Properties and Sesame Water Use Efficiency

“…Quansah (2010) similarly reported that application of poultry manure in combination with household waste onto the soil significantly increased its moisture retention due to added organic matter into the soil. Liu et al (2013) and Tilahun et al (2013) similarly found that incorporation farm yard manure into soil significantly reduced SBD and yet at the same time significantly increased SMC due to large amounts of organic matter and organic carbon added on the soil.…”
