“…Amending such soils with suitable composts may improve the medium for turfgrass growth. Composted poultry litter (CPL) contains several plant macronutrients and micronutrients and has been considered as a valuable soil amendment to enhance soil fertility, organic matter, and tilth [2][3][4][5][6]. Improper use and disposal of poultry litter may have detrimental effects on environment and human health.…”

During construction disturbance, topsoil is often removed and turfgrasses are established in poor soils. Our study determined the effects of amending subsoil with composted poultry litter on physical and chemical properties that affect turfgrass growth attributes. To simulate typical disturbance conditions, 20 cm of topsoil was removed from a Dormont silt loam (fine-loamy, mixed, superactive, mesic Oxyaquic Hapludalfs) and composted poultry litter was incorporated at 0.1, or 0.2, or 0.4 cm/cm-soil into the exposed subsoil to a depth of 12.7 cm before growing turf. Composted plots were compared to N-fertilized (50 × 10 −4 kg m −2 ) and control plots. Linear increases in total water content, organic matter, pH, and basic cations were observed following compost incorporation. Composted poultry litter increased total water content by 38% and decreased soil bulk density by 42%. Compost applications increased organic matter by 5.8%-6.4%, along with an increase in pH from 6.0-7.4. The cation exchange capacity increased up to 186% in compost-incorporated plots. No differences were observed between fertilized and control plots for all soil properties except for P levels, which increased in fertilized plots. Overall, compost treatments improved soil physical and chemical properties compared to conventionally fertilized and control plots.

“…Studies on the relative effect of tillage cum poultry manure applications on soil properties and cocoyam yield is scarce. Nyakatawa et al (2001) has reported that it is possible to increase yield of crops on degraded soils by using organic manure for soil fertility improvement after adopting appropriate tillage method. This study is to assess the impact of tillage and poultry manure on the leaf nutrient concentration, growth and corm yield of cocoyam on an Alfisol of southwest Nigeria is expected to provide information on soil management requirement of cocoyam.…”

“…Nyakatawa et al (2001) suggested that it is possible to increase yields of crops on physically degraded soils by using organic resources such as manure for soil fertility improvement after adopting appropriate tillage systems. Appropriate soil tillage or seedbed type can be a suitable alternative to enhanced nutrient availability to crop and therefore reduce money spend on chemical fertilizers (Adekiya and Ojeniyi, 2002).…”

Abstract:Research study on the effect of tillage systems and application rate of poultry manure on sweet potato (Ipomoea batatas) in Alfisol of southwest Nigeria is lacking. Field trials were conducted in 2006, 2007 and 2008 cropping seasons on an Alfisol (Oxic Tropuldalf) at Owo in rainforest zone of southwest Nigeria. The trials consisted of the factorial combinations of two tillage methods (manual clearing and conventional tillage) and four manure levels (0, 5, 10 and 15 t/ha) arranged in a randomized complete block design and replicated three times. Conventional tillage alone (CTo) resulted in lower soil N, P, K, Ca, Mg and soil organic C and better leaf N, P, K, Ca and Mg concentrations, growth and yield of sweet potato compared with manually cleared (MCo) plots. The better performance of sweet potato under conventional tillage (CTo) was adduced to reduced bulk density. Bulk density was negatively correlated with yield. Conventional tillage alone (CTo) improves sweet potato tuber yield by 62, 55 and 42% in 2006, 2007 and 2008, respectively compared with manual clearing alone (MCo). In both the manually cleared and conventionally tilled plots, soil organic C, N, P, K, Ca, Mg and water content increased with amount of poultry manure, while soil pH, bulk density and temperature were reduced. Yields given by 5, 10 and 15 t/ha poultry manure were not significantly different under both manually cleared and conventionally tilled treatments. Conventional tillage plus 5 t/ha poultry manure (CT+5 PM) produced the highest overall yield. Compared with manual clearing alone (MCo) and conventional tillage alone (CTo), conventional tillage plus 5 t/ha poultry manure (CT+5 PM) improved tuber yield of sweet potato by 117 and 43%, respectively. Therefore the use of 5 t/ha poultry manure with conventional tillage is recommended for sweet potato production on an Alfisol of southwest Nigeria. Keywords
