“…The addition of manure and other organic sources to the soil reduces the capacity of P adsorption, increases the available content and promotes greater mobility in the soil profile of soluble organic forms of P. This is more evident for nutrients that are preferentially transported through diffusion, as in this case, because the driving force of this type of transport is the gradient of concentration of the element between the rhizosphere and its surrounding area (Novais et al, 2007). The higher porosity, resulting from the increase of micro-and macro-faunas of the soil, due to the high doses of organic material, also contributes to increasing the diffusive flow of nutrients in the soil, which also promotes, besides the supply of nutrients, the stimulus to the biological activity, potentiating water retention and the formation of aggregates (Nardi et al, 2004). In the treatment without manure application, the amount extracted/exported by the cactus pear was 17 kg ha -1 .…”

A B S T R A C TThis study aimed to evaluate the extraction/exportation of macronutrients by cladodes of 'Gigante' cactos pear, grown under diferente spacings and doses of cattle manure applied to the soil 600 days after planting. Twelve treatments were used, three spacing (1.00 x 0.50; 2.00 x 0.25 and 3.00 x 1.00 x 0.25 m) and four doses of cattle manure (0, 30, 60 and 90 Mg ha -1 year -1 ), arranged in a 3 x 4 factorial scheme in randomized blocks, with three replicates. The extraction/exportation of N, P, K, S, Ca and Mg was determined, whose respective values for maximum dry matter production (21.8 Mg ha -1 ), with a cattle manure dose of 71.8 Mg ha -1 year -1 were: 287.9, 46.2, 924.2, 40.7, 609.7 and 249.1 kg ha -1 , 600 days after planting. The amounts extracted/exported from N, P, K and Ca varied independently with spacings and manure doses, while Mg and S were dependent on the interaction between factors. The doses of manure are insufficient to meet the demand of extracted/exported K, Ca and Mg. The increments in the doses promote greater nutrient uptake by the plant. The extracted/exported macronutrients in largest amounts are: K, Ca, N, Mg, P and S, in this order. Extração/exportação de macronutrientes por cladódios de palma forrageira 'Gigante' sob diferentes espaçamentos e adubação orgânica R E S U M O Objetivou-se, com este trabalho, avaliar a extração/exportação de macronutrientes por cladódios colhidos da palma forrageira 'Gigante' , cultivada sob diferentes espaçamentos e doses de esterco bovino aplicadas ao solo aos 600 dias após o plantio. Foram utilizados 12 tratamentos, três espaçamentos (1,00 x 0,50; 2,00 x 0,25 e 3,00 x 1,00 x 0,25 m) e quatro doses de esterco bovino (0; 30; 60 e 90 Mg ha -1 ano -1 ), dispostos em fatorial 3 x 4 num delineamento em blocos casualizados e três repetições. Determinaram-se a extração/exportação de: N, P, K, S, Ca e Mg cujos respectivos valores para máxima produção de matéria seca (21,8 Mg ha -1 ), com uma dose de esterco de 71,8 Mg ha -1 ano -1 foram: 287,9; 46,2; 924,2; 40,7; 609,7 e 249,1 kg ha -1 , aos 600 dias após plantio. As quantidades extraídas de N, P, K e Ca variaram de forma independente com espaçamentos e doses de esterco enquanto as de Mg e S foram dependentes da interação entre os fatores. As doses de esterco são insuficientes para atender às quantidades extraídas/exportadas de K, Ca e Mg. Os incrementos nas doses promovem maior extração de nutrientes pela planta. Os macronutrientes extraídos/ exportados em maior quantidade são: K, Ca, N, Mg, P e S, nesta ordem.

“…The results of several long-term studies have shown that the addition of compost improves soil physical properties by decreasing bulk density and increasing the soil water holding capacity (Weber, 2007). Moreover, in comparison with mineral fertilizers, compost produces significantly greater increases in soil organic carbon and some plant nutrients (Nardi, 2004).Totally, according to result, S.C 704 had best results and it treatment showed highest plant height (221.6 cm), number of seeds (773.4),1000-seed weight (150.46 g), seed yield (9.7 t ha -1 ), biological yield (19412 kg/h), harvest index% (50.36%). Between vermicomposttreatments,application of 75% led to 61, 43, 73, 65, 80 and 80 percentage of highest plant height, number of seeds, 1000-seed weight, seed yield, biological yield, harvest index% in compare to control.…”

“…In addition, in our cattle-breeding farm, rotations were usually longer than in sheep breeding farms, where the main rotation type was based on continuous winter cereals associated or not with one-year clover. In line with West and Post (2002) and Nardi et al (2004), the incorporation of crop residues did not seem to have a relevant effect on the SOM balance. Here, the only case when the OM inputs were significantly different was when we compared farms with or without livestock.…”

Factors affecting soil organic matter conservation in Mediterranean hillside winter cereals-legumes cropping systems

et al. 2012

Soil conservation is an important issue for farming and environmental protection in Mediterranean areas. Hillside farming systems, based on winter cereals and legumes, are common in these areas and are the target of several environmental policies. Soil organic matter (SOM) is widely used to assess the environmental performance of these cropping systems. Nevertheless, few studies have considered soil conservation practices in hillside systems in terms of implementing more effective agro-environmental policies for these areas. This paper compares the SOM conservation of different winter cereal based cropping systems within Mediterranean hillside crops/livestock farms. Seventeen cropping systems were characterised by on-farm surveys in the inland hilly area of Grosseto (Tuscany, Italy). For each cropping system, we performed a SOM balance, based on Hénin-Dupuis' equation, using either local environmental databases or data from on-farm surveys. Differences between cropping systems were analysed by the Kruskal-Wallis test. On average, the cropping systems identified did not guarantee SOM conservation and varied considerably from farm to farm, however, some practices seemed to have a positive performance, e.g. cropping systems of cattle farms. According to the literature, annual SOM balance differs significantly depending on crop rotation length and longer crop rotations performed better than shorter ones. However, we found a local effect indicating that this better performance was influenced by local farmers' cooperatives, which to some extent counteracted the negative effect of crop rotation length. There were significant differences in the performance of dairy sheep and cattle farms (-1031 kg ha -1 yr -1 vs +103 kg ha -1 yr -1 , respectively). This suggests that the presence of livestock did not have the same favorable effect on soil conservation in Mediterranean systems and that this factor should be more investigated. Surprisingly, in our sample, for the same crop rotation length, livestock density did not affect the annual SOM balance. Due to the high variability in local cropping systems and soil characteristics, further surveys on a larger farm sample and field soil measurement are needed to confirm these trends and validated the regional soil database. However, our results shed light on the soil conservation effects of Mediterranean hillside cropping systems of winter cereals and legumes, and could support the local implementation of agro-environmental measures.
