“…Statistical analyses showed that the available P and K contents of the CPRR soil were significantly heightened (p<0.05). These results suggested that the CPRR treatment enhanced the fertility of the soil, an observation in agreement with previous studies (Kowaljow and Mazzarino, 2007;Courtney and Mullen, 2008;Sommer et al, 2011) reporting that residue returned as compost increased the organic matter and N, P and K contents of soil. However, a significant difference was not observed for the organic matter and available N when compared with CK in the present work.…”

Abstract:A field experiment was conducted to investigate the influence of composted pineapple residue return (CPRR) on soil bio-chemical properties and the growth performance of next-cropped pineapple plants. The results suggested that CPRR markedly decreased the soil bulk density and increased the contents of available P and K. CPRR significantly increased the abundance of bacteria and actinomycetes, and the activities of catalase, acid phosphatase and invertase in the soil were notably heightened. Growth characteristics, including the plant height, length of leaves and roots, leaf width, number of leaves and fresh weight of the aboveground and belowground parts were significantly increased by CPRR. The contents of chlorophyll, soluble sugars, and soluble protein, as well root vigor were also markedly increased. CPRR also increased the fruit transverse and longitudinal diameters, weight and yield of next-cropped pineapple.

“…In a previous study carried out at Tel Hadya, it was shown that SOC was significantly increased by application of large amounts (10 Mg/ha/2 yr) of compost and less intensive tillage [6]. However, production and availability of compost at such amounts exceeds the limits of biomass and manure production of this agro-ecosystem and thus is not a feasible option for farmers, unless compost is produced elsewhere and imported.…”

“…To mitigate the negative impact of such intensification, various management practices have been developed, such as rotations as an alternative to mono-cropping [3], reduced tillage or no/zero tillage (NT, ZT) instead of conventional tillage (CT) [4] [5], the production and use of compost from manure, straw and other organic residues [6] or development of fertilizer best management practices [7]. In a major shift from conventional production systems, conservation agriculture (CA) systems, embracing ZT for minimal soil disturbance, surface residue retention and crop rotation, have been adopted extensively in Australia, Canada, the USA and Latin America [8] [9].…”

“…Few studies have been published so far focusing on soils of the Mediterranean region and how they are affected by ZT/CA practices [6] [21]- [23]. Therefore, in the long-term ZT/CA trials at ICARDA's headquarters at Tel Hadya in Syria, a range of soil quality indicators were regularly monitored during 2008 to 2012, to help explain increases in crop yields that were observed under the various ZT systems.…”

“…Other studies have further highlighted the beneficial aspects of straw biomass retention for the surface during the dry season when the biomass is not needed for feeding livestock [19]. Additionally, fodder yield improvements have been demonstrated [20] from barley and vetch (Vicia sativa) intercrops in dryland Syria, with reduced tillage and barley straw used as surface ground cover.…”

This paper reports on early soil related outcomes from conservation agriculture (CA) benchmark sites located within the marginal rainfed environment of agro-ecological zone 4 (annual rainfall: 200-250 mm) in pre-conflict central Syria. The outcomes reported are specifically those that relate to beneficial soil quality and water retention attributes relative to conventional tillage-based soil management practices applied to the fodder barley-livestock system, the dominant system in the zone. On-farm operational research was established to examine the impact of a barley (Hordeum vulgare) and vetch (Vicia sativa) rotation intercropped with atriplex (Atriplex halimus) and salsola (Salsola collina), under CA and conventional tillage agriculture, on the soil quality parameters and crop productivity. Preliminary results showed that CA had a positive effect on the soil quality parameters and crop performance. The soil moisture and hydraulic conductivity were higher under CA (p < 0.05), combined with improved productivity (grain and above-ground biomass) under specific crop mixes. The results suggest that despite the marginal nature of the zone, the use of CA is a viable option for the future of farmers' livelihoods within similar localities and agro-climates, given the benefits for soil moisture and grain and straw productivity. In addition, it is likely to positively impact those in marginal environments where both pastoralism and agro-pastoralism production systems co-exist and compete for crop biomass as a main source of livestock feed. The increase in grain and straw yields vis-à-vis improvements in biophysical parameters in the CA system relative to tillage agriculture does suggest, however, that the competition with livestock for biomass is likely to reduce over time, and farmers would be able to return increased levels of straw (as stubble and residue) as mulch, given improved biomass yields.
