“…It should be noted that HMV showed an EI lower than 0.1 on all the evaluation dates, and DCM showed N immobilization (14 to 56 days). In a study on mineralization and the N efficiency index of cattle manure fertilizers, Eckhardt et al (2016) found EI of 0.27, 0.23, and 0.22 for cattle manure compost, cattle manure vermicompost, and cattle manure, respectively.…”

The efficiency index (EI) refers to the ratio of nutrients mineralized/made available in the soil to the total amount of nutrients added by organic fertilizer. Therefore, understanding the EI is essential for recommendation of organic fertilization. The aim of this study was to evaluate the availability through mineralization and the efficiency index of nitrogen (N), phosphorus (P), and potassium (K) in organic fertilizers produced from cattle manure. The following treatments were evaluated in an incubation experiment under controlled conditions: soil without fertilizer (control); soil + beef cattle manure vermicompost; soil + beef cattle manure/straw compost; soil + beef cattle manure; soil + dairy cattle manure; and soil + vermicompost produced under conditions of high moisture and forced air. Nitrogen and P mineralization and K availability in the soil were evaluated at 0, 7, 14, 28, 56, 112, 224, and 365 days. Nitrogen availability in the soil increased after the bioconversion of cattle manure by composting, whereas phosphorus availability increased by vermicomposting. The average efficiency indices of N, P, and K of the fertilizers produced from cattle manure were 16, 57, and 82 %, respectively. These efficiency indices are lower than the values presented by the Liming and Fertilization Manual for the states of Rio Grande do Sul (RS) and Santa Catarina (SC), Brazil.

“…In this way, 80% of the total N of PS (an availability factor of 0.80) is estimated as plant-available N in South Brazil, in the first years after application (CQFS-RS/SC, 2004). On the other hand, this guideline was obtained from a restricted number of studies (Eckhardt et al, 2016), and all related to annual crops. There are also recommendations on perennial pasture.…”

A B S T R A C TThis study evaluated the response of carpet grass to pig slurry fertilization in order to estimate the agronomic efficiency and the plant-available nitrogen (N) of such manure. A field test was conducted during two years, following a randomized block design with six replicates of the treatments: 0, 100, 200, 300, 400 and 500 kg N ha ). The average agronomic efficiency of the manurewas 15 kg DM kg -1 N and it was lower than that found with ammonium nitrate (27 kg DM kg -1 N).The estimated plant-available N of the pig slurry was similar between the growing years. The N fraction of this manure available to the pasture was 0.64 (2008-09) and 0.60 (2009-10).Dejeto líquido de suínos em pastagem de grama-tapete: Produção e nitrogênio disponibilizado R E S U M O Este estudo avaliou a resposta da grama-tapete à aplicação de dejeto líquido de suíno para determinar a eficiência agronômica e estimar a disponibilidade de nitrogênio desse esterco. O experimento foi realizado em condições de campo durante dois anos, em delineamento em blocos ao acaso, com seis repetições dos seguintes tratamentos: 0, 100, 200, 300, 400 e 500 kg N ha -1 ano

“…ICL had higher mite density than NP and NT, while EU had higher Collembola density than ICL, ICLF and NT (Table 3). Cattle dung combined with straw increase N mineralization in soil [38], which can positively affect Acarina and mesofauna density in grazed systems, such as observed in ICL and ICLF.…”

Abstract:The soil mesofauna plays a role in organic matter comminution and decomposition, and can be used as bioindicators, since they are sensitive to soil management, vegetation and climate changes. Hence, this study aimed to evaluate mesofauna density and diversity in different land use systems to identify faunal relationships with soil properties, management and seasonality. The study area included five land use systems in Ponta Grossa municipality, Paraná State: integrated crop-livestock (ICL), integrated crop-livestock-forestry (ICLF), grazed native pasture (NP), Eucalyptus dunnii plantation (EU) and no-tillage (NT) cropping systems. In each system, eight soil samples for mesofauna were collected with Berlese funnels of 8 cm diameter along a transect in three replicate plots of 50 m × 100 m. For physical and chemical analysis, soil was sampled at five points per plot in two seasons: winter 2012 and autumn 2013. Data were statistically analyzed using ANOVA and Duncan's test (P < 0.05), nonparametric statistics (when necessary) and redundancy analysis (RDA). Diversity was calculated based on the group richness and Simpson index. The main mesofauna groups found were: Acarina, Collembola and Hymenoptera. Diplopoda, Enchytraeidae, Isopoda, Collembola, Hemiptera, Hymenoptera and Coleoptera larvae were more abundant in autumn than winter. Soil moisture was the main factor responsible for higher mesofauna abundance in autumn. Integrated production systems, especially ICLF had similar invertebrate community abundance and composition with EU, while NT favored Oribatid mites, although the use of insecticides, herbicides and fungicides reduced total mesofauna density. Most correlations between mesofauna and physical-chemical attributes in the winter were not observed in the autumn and vice versa, revealing that there are more factors involved in regulating soil mesofauna distribution.
