AbstractSoil fertility decline represents a major constraint to crop productivity in sub-Saharan Africa. Many studies have shown that addition of biochar or compost can effectively improve soil quality. Biochar produced from crop residues are often N-poor but rich in stable C while poultry manure composts, which is often rich in nutrients including N decomposes rapidly under high rainfall and temperature conditions. Combined biochar and compost application can compensate for the shortcomings of each other such that their interactive effect is likely to improve soil quality. A 30-days incubation experiment was carried out on a Haplic acrisol amended with corn cob biochar, rice husk biochar, coconut husk biochar, poultry manure compost and composted rice husk or corn cob biochar to examine the effect of compost and biochar, applied singly, in combination or as co-compost on basal soil respiration, and soil quality indicators such as soil pH; soil microbial carbon; cation exchange capacity; total organic carbon, total nitrogen and available nitrogen concentration. The results showed that addition of the different amendments increased soil pH compared with the untreated control with the combined corn cob and rice biochar and compost treatments recording the highest pH values. Basal respiration following sole compost, composted biochar and combined biochar and compost application were significantly greater than the sole biochar and the control treatments. TOC increased by 37% in the sole compost treatment to 117.3% in the combined corn cob biochar and compost treatment, respectively. MBC increased by 132.2% in the combined rice husk biochar and compost treatment and by 247% in the sole compost treatment compared to the control. The study has demonstrated the potential of compost, biochar and especially composted biochar to enhance soil quality, C stabilization and reduce soil C loss through basal respiration.

The response of corn (Zea mays L.) to manure that had been treated to minimize odor was investigated in a greenhouse trial with two silt loam soils of pH 4.2 and 7.1. Pretreatment of manure resulted in sources initially high in organic N and NH4+, but low in NO3−. One pretreatment gave high initial NO2− concentrations. In soil at pH 4.2, NH4+ was the major N source utilized by corn grown to 36 days, and dry matter yields were superior to those from soil at pH 7.1 where soluble NO3− was the major source of N. At pH 7.1, NO2− remained in significant quantities and decreased dry matter yields at 6 wk. Soil inorganic N concentrations varied between soils and was attributed to soil pH differences. Rate of NO2− disappearance decreased with increase in soil pH, and NH4+ accumulation increased with decrease in soil pH, whereas NO3+ production was favored by neutral pH conditions. Some NO3− production was observed in pH 4.2 soil after 36 days' incubation

Application of animal manures for soil amendment plays a major role in the improvement of soil properties and enzymatic activities of a degraded Ultisol. This study assessed the effects of poultry manure (PM) and swine manure (SM) on the activities of catalase and urease enzymes and some soil properties. The PM and SM were applied at the rate of 30 t ha–1 each on experimental plots arranged in a randomized complete block design with three replicates. Soil samples were collected at day 0, 14, 28, 42, 56, 70 and 84 from 0-15 and 15-30 cm depths and analyzed for catalase and urease enzymes and some soil properties using standard procedures. The results showed increase in soil pH (in H2O) from 4.0 to 5.4 following manure application. At 0-15 cm soil depth, PM and SM recorded 28.1 and 28.8% increases in soil pH (in H2O), respectively. Soil organic carbon was highest (2.6 g kg–1) at 0-15 cm depth for soil amended with SM while the lowest value of 1.1 g kg–1was obtained at 15-30 cm depth for soil unamended with SM. In PM-amended soil, catalase activities ranged from 1.32 to 6.77 mg g–1 while its activities in SM-treated soil significantly (p < 0.05) varied between 1.55 and 8.11 mg g–1. Urease showed ranges of 0.72-3.90 mg g–1 and 0.96-4.71 mg g–1 in PM-amended and SM-treated soils, respectively. The results uphold that animal manures improve soil properties and are enzymatically controlled.

Cultivating a land without proper crop management may lead to diminished organic carbon. Thus, this study assesses the effects of long-term farming (2014 to 2018) on soil OC. This study was conducted in Share Farm II, Universiti Putra Malaysia Bintulu Sarawak Campus on a selected area that practiced crop rotation. Soil samples have been collected according to grid sampling techniques by beds row and inter-row, and are analysed for soil pH, OM, TOC, and total N. The results show a trend in the alleviation of soil acidity with 2018 > 2016 > 2014, however, there is a diminished of TOC as the year of cultivation increases from 3.42% to 1.87%. The results show insufficient crop residue that returns to the soil system which has been subjected to flash flood and poultry manure application. In return, C retention ability was reduced, which further limit OM capability to supply nutrients upon decomposition. The correlation analysis has revealed that different types of crop residue such as grass clippings that have been applied in 2016 may be another reason for the insufficient N availability (0.44%). Therefore, the quantity and quality of residues may affect the decomposition rate and provide a lower C/N ratio, which significantly affects the soil pH, total N, and other nutrients that are essential for crop uptake.

Potential adjacent coal mine paddy soils often endure low soil and plant productivity through unscientific mining activities causing acid mine drainage. But the extent of its effect to soil is not known, therefore the study was taken to characterize coal mine affected lowland fields on the basis of soil acidity, identify the best amelioration practices and evaluate the performance on rice productivity at farmers’ field level. An experiment with a completely randomised block design (5 replicates) was performed to determine the effects of poultry manure (PM), compost (C), lime (L), paper mill sludge (PMS) and microbial consortium (MC) with their suitable combination through pot experimentation at College of Post Graduate Studies followed by the preeminent selected practices at field trials at Khliehriat, Meghalaya. The factors used were PM and C (10 t ha-1), L as CaCO3, PMS (250 and 500 kg ha-1) and MC were incorporated at appropriate rates. On categorization, two locations were found to exhibit extremely pH acid soil (pH 4.51 ± 0.51) i.e. Moonlakhep (L1) and ultra pH soil (pH 3.14 ± 0.23) i.e. Ladrymbai (L2). Integration of practices showed significant increase in soil acidic indices such as soil pH by 6% to 23% and significant decrease in exchangeable acidity by 49% to 18% with T4 at both locations. Confined increases of soil organic carbon by 12% to 40% with enhanced available soil nutrients by 40% at high optimum rates were noticed. Yield attributes were significantly influenced by different treatments. Highest plant height (83.58 cm and 81.32 cm), grain yield (3436 kg ha-1 and 3120 kg ha-1) were recorded under the practices of T4. However, stover yield (7875 kgha-1) was noticed in T8 at L1 and at L2 maximum in T4 (7420 kgha-1). Soil acidic indices, nutrient and crop growth were influenced at high optimum rates of soil amendment and enhanced with PM amended soil.

Effects of four organic amendments on some soil physical and chemical properties were investigated in Awka, Anambra State in southeastern Nigeria. Over the years, use of synthetic materials in crop production has been a common practice globally. The attendant detrimental effects of the chemicals used in the formulation of these synthetics on animal and human health as well as the environment has made researchers to look out for a better agronomic practice that would not only improve productivity but at the same time sustain a healthy environment. Sole maize, sole cowpea and maize-cowpea intercrop (study area conventional practices) were planted using four soil organic amendments viz: cassava peel (CP), poultry manure (PM), pig waste (PW) and rice husk (RH) at the rate of 20 t ha–1 with the fifth as the control. The treatments were laid out in a 3 × 5 factorial in randomized complete block design and replicated four times. Data on the treatments’ effects on the selected soil physical properties (bulk density, total porosity, soil moisture) and chemical properties (soil pH, available phosphorus, cation exchange capacity (CEC), organic carbon, exchangeable bases and exchangeable acidity) were subjected to factorial analysis of variance using GenStat 2006 Edition. Results indicated that for sole maize, the amendments had significant effect onexchangeable Al3+and Na+; organic carbon, soil pH, available phosphorus and CEC but had no significant effect on Ca2+, H+, Mg2+ and K+ as compared to the control. For sole cowpea, compared to the plots with no amendment (control), all the chemical parameters analyzed differed significantly except organic carbon. Whereas, for maize-cowpea intercrop the treatments had no significant effect on Al3+, Na+, K+ and available phosphorus but differed significantly in exchangeable H+, Ca2+, Mg2+, organic carbon, soil pH, and CEC. There was a decrease in bulk density following the amendment. For sole maize, sole cowpea and maizecowpea intercrop; bulk density, total porosity and moisture content of the amended plots were significantly (p< 0.05) influenced. Organic amendments also significantly improved the growth and yield of maize and cowpea in both the sole and intercrop systems. Generally, poultry manure resulted in higher plant height,number of leaves and leaf area for maize; vine length, number of branches for cowpea as compared with other amendments. Hence, poultry manure was the most effective organic amendment in improving the soil physical and chemical properties as well as the growth and yield of cowpea and maize.

A short-term (3-day) equilibration experiment was carried out to determine the effects of 3 animal manures (poultry, pig, and cattle) added at a rate of 20 mg/g to an Oxisol on pH and the concentrations of total (AlT) and monomeric (AlMono) Al in solution. The pH of equilibrium solutions from the control, cattle, pig, and poultry manure treatments were 4.0, 4.6, 5.2, and 6.3, respectively. AlMono concentrations decreased progressively as pH increased but concentrations of AlT were similar in the pig and poultry manure treatments. Subsequent equilibration experiments examined the solubility of AlMono and AlT when the 3 manures were added to the Oxisol or a 40 um AlCl3 solution and pH was maintained at 4.0, 4.5, 5.0, 5.5, 6.0, and 6.5. In both experiments, addition of manures generally tended to reduce the concentration of AlT in the lower pH range (4.0 and 4.5) but increase it in the higher range (pH 5.5 or 6.0 and above). Concentrations of AlMono, and the proportion of AlT present as AlMono, were reduced over the whole pH range. Results were explained in terms of the strong bonding ability of organic matter in both the solid and solution phases for Al. At lower pH, where Al is highly soluble, complexation by solid-phase organic matter results in a reduction in both AlT and AlMono. However, at higher pH, where Al solubility becomes limited, complexation of Al by soluble organic matter becomes an important mechanism and this results in an elevation in AlT, while concentrations of AlMono remain very low. It was concluded that the effects of manures in reducing concentrations of AlMono in soil solution are attributable to both an increase in pH and the complexing ability of organic matter for Al.

The study was done to quantify the effect of uncovered field storage of solid poultry manure in south coastal British Columbia on a site where solid Turkey manure was stored uncovered each fall and winter for approximately 6 yr. The soil was sampled to 370 cm depth in a transect with six sampling locations: two in the manure storage area, and two on either side of the manure storage area. The soil was analyzed for the concentrations of total organic C, total Kjeldahl N, ammonium, nitrate, K, P, Mg, and Na in addition to soil pH and electrical conductivity. The mass of nutrients to 370 cm depth was 39 700 and 330 kg NH4+–N ha−1, 500 and 480 kg NO3−–N ha−1, 36 400 and 1440 kg K ha−1, 12 100 and 2190 kg P ha−1, 3150 and 1140 kg Mg ha−1 and 9850 and 975 kg Na ha−1 for the manure storage and non-storage sampling locations, respectively. The depth weighted average soil pH was 8.4 and 4.7 and average soil electrical conductivity was 3.3 and 0.3 dS m−1 for the manure storage and non-storage sampling locations, respectively. The lack of an increase in soil nitrate concentration in the manure storage area was attributed to concentrations of free ammonia in soil solution toxic to nitrifying bacteria. The results highlight the high potential for nutrient loss from uncovered fall and winter field storage of poultry manure in south coastal British Columbia.

Application of animal manures influences enzymatic activities and microbial dynamics in soils. Poultry manure (PM) and swine manures (SM) were applied at the rate of 30 t ha−1 each. The experiment was arranged in a randomized complete block design with three replicates. Soils were sampled at day 0, 14, 28, 42, 56, 70 and 84 from 0-15 cm and 15-30 cm depths. In both the PM and SM amended soils, significant increase in soil pH was observed. In PM treated soil, alkaline phosphatase significantly increased from 0.38 Mg g-1 to 4.94 Mg g-1 whereas in SM treated soil, it increased from 1.21 Mg g-1 to 4.80 Mg g-1. Acid phosphatase significantly increased from 0.42 Mg g-1 to 3.02 Mg g-1 in PM amended soil while increases from 0.11 Mg g-1 to 2.38 Mg g-1 were observed in SM amended soil. The application of PM and SM increased Total Heterotrophic Bacterial Count significantly from 1.27×104 Cfu g-1 to 8.63×107 Cfu g-1 and from 1.40×104 Cfu g1 to 8.10×107 Cfu g-1, respectively. Total Fungal Count significantly increased from 1.63×103 Cfu g-1 to 4.67×106 Cfu g-1 and from 2.00×103 Cfu g-1 to 5.67×106 Cfu g-1 in PM and SM amended soils, respectively.
