“…In the case of the ORG farms surveyed in this study, it was considered that a certain amount of organic fertilizer was added to make up the scrimpy fertility effect compared with chemical fertilizer. Furthermore, several studies also reported an increase in available phosphorus upon ORG amendment 16,20,22) . Jiao et al described that organic acids derived from manure, chelate Fe and Al oxides, result in leaching thereby reducing the number of binding sites for phosphate on the surface of soils 16) .…”

Comparative Analysis of Environmental Variability and Fungal Community Structure in Soils between Organic and Conventional Commercial Farms of Cherry Tomato in Japan

et al. 2008

Soil environmental variability and fungal community structures were analyzed to evaluate differences in soils managed under organic (ORG) and conventional (CNV) systems of farming in Fukushima and Yamagata prefectures in Japan. The soils were collected from 8 ORG and 13 CNV farms in 2005, and 6 ORG and 13 CNV farms in 2006. Principal component analysis (PCA) of 26 environmental variables demonstrated that plots of ORG and CNV were separated; however, the differences were unclear. Environmental variability and scores of principal components indicated more MgO, available phosphorous, NO 3 -N, and K 2 O in ORG than in CNV, and more silt, Mn, and Mg/K in CNV than in ORG. The differences were considered distinguishing for these farming systems. The fungal DGGE profiles and characteristic band intensities could not be used to distinguish between ORG and CNV. However, the PCA of band profiles slightly differentiated the plots of each system for both 2005 and 2006, as was the case for environmental variability. Furthermore, analysis of the PCA scores revealed several characteristic bands in DGGE profiles. A sequence analysis of the characteristic bands indicated the genus Mortierella sp. and close relatives of Cheatomium globosum to be characteristic fungi in CNV, although definitive characteristic fungi were not found in ORG. Since these results were obtained from soils differing in the type and amount of fertilizer, the application of pesticide, and management system, they are considered to reflect the general difference between ORG and CNV soils.

“…Each factorial plot was split into four strips (20 m by 6 m) and four fertilizer treatments [0,5,10 and 15 Mg ha (1 (dry weight basis) of composted cattle manure] were applied randomly to the split plots. As described by Jiao et al (2007), the 15 Mg ha (1 compost application provided 45 kg plant-available P ha (1 , equivalent to silage corn P requirements. Plots received supplemental inorganic fertilizers, and the target nutrient inputs were 200 kg N ha .…”

. 2008. Soil organic carbon and nitrogen pools as affected by compost applications to a sandy-loam soil in Quebec. Can. J. Soil Sci. 88: 443Á450. Compost contributes plant-available nutrients for crop production and adds partially decomposed carbon (C) to the soil organic carbon (SOC) pool. The effect of compost applications and other agricultural practices on SOC and total nitrogen (N) pools was determined in a sandy-loam Humic Gleysol at the Research Farm of McGill University, Ste-Anne-de-Bellevue, Quebec. Experimental plots with continuous silage corn (Zea mays L.) and silage corn-soybean (Glycine max L. Merr.) production were under conventional tillage (CT) or no-tillage (NT) management. Composted cattle manure was applied each spring at rates of 0, 5, 10 and 15 Mg (dry weight) ha(1 and supplemental NPK fertilizers were added to meet crop requirements. The C input from crop residues was affected by tillage, crop rotations and compost application, but differences in the SOC and total N pools were due to compost applications. After 5 yr, compost-amended plots gained 1.35 to 2.02 Mg C ha(1 yr (1 in the SOC pool and 0.18 to 0.24 Mg N ha(1 yr (1 in the total N pool, as compared with initial pool sizes when the experiment was initiated. These gains in SOC and total N were achieved with agronomic rates of compost and supplemental NPK fertilizers, selected to match the phosphorus requirements of silage corn. Such judicious use of compost has the potential to increase the SOC and total N pools in agroecosystems under annual crop production.

“…Compost containing treatments reduced PSI and increased MBC and DOC. A combination of anion sorption site saturation with added phosphate, competitive inhibition of anion sorption sites by organic acid anions, reduction of Al 3+ activity through chelation, and reductions in exchangeable acidity via exchange of surface hydrogen by Ca 2+ likely contributed to reduce sorption in soils receiving compost (Iyamuremye et al, 1996a;Nziguheba et al, 1998;Hunt et al, 2007;Jiao et al, 2007). Labile Pi showed a strong correlation with PSI, as anion sorption sites occupied with labile Pi inhibited additional sorption.…”

Core Ideas Phosphorous fertility was evaluated in weathered volcanic soil in winegrape production. Seasonal Hedley P fractionations, P sorption, microbial biomass carbon, and DOC were investigated. Application of compost, alone or with TSP, reduced sorption and increased MBC. Labile Pi responded significantly to fertilization despite advanced pedogenesis. Significant labile Pi response in weathered soil may be due to low‐Fe lithology. Phosphorus dynamics and management strategies were investigated in a strongly weathered rhyolitic soil in the northern Coast Ranges of California. Recent conversion of upland, native oak (Quercus spp.) woodland ecosystems to winegrape production has led to a P deficiency in these soils. We investigated the growing season behavior of Hedley phosphorus fractions, the P sorption index (PSI), microbial biomass C (MBC), and dissolved organic C (DOC) in response to a single P application from three sources: composted steer manure (CSM), triple superphosphate (TSP), and mixed compost and triple superphosphate (MIX). Phosphorous sources, equal in P application rate (39 kg ha−1), were applied in the winter of 2012, and soils were sampled in spring, summer, and fall. Labile inorganic P (Pi) (resin Pi + NaHCO3 Pi), Fe/Al‐Pi (NaOH Pi), and total P were significantly (p < 0.01) increased by P application, regardless of source. Calcium‐Pi (HCl Pi), DOC, MBC, and pH were increased, and PSI was reduced, by compost addition. Net extractable Fe/Al‐Pi increased during the study period. Moderately labile organic P (Po) (NaOH Po) declined, independent of fertilization, reflecting background soil P cycling. Calcium‐Pi totals were low (mean 9 mg kg−1 for untreated plots), and other indicators of chemical weathering were high, suggesting an advanced stage of pedogenesis with respect to Walker–Syers P availability. In spite of advanced pedogenesis, labile Pi increased significantly from fertilization and remained elevated throughout the growing season. Results of this study inform P management in highly weathered, P‐fixing soils experiencing P deficiencies.
