“…In addition, in the Mediterranean climate region, the annual rainfall distribution and the water deficit at the end of the growing season is other limiting factor for cereal production, due to the low water infiltration and low root biomass in compacted soils (Sojka et al, 1993;Hong-ling et al, 2008;Alvarez and Steinbach, 2009;Vidhana Arachchi, 2009). Therefore, no tillage combined with subsoiling (Nt+Sb) is particularly relevant in these environments where much of crop growth occurs in spring (at the start of the dry season) and is generally subjected to a water deficit during the grain filling-period of cereals (De Vita et al, 2007;He et al, 2009;Jin et al, 2009).…”

“…On the contrary, conservation tillage systems in rainfed Mediterranean environments avoid crusting and increase water infiltration (Riezebos and Loerts, 1998;Lampurlanés et al, 2001;Pansak et al, 2008;Fuentes et al, 2009;Vidhana Arachchi, 2009). Ramos and Martínez-Casasnovas (2006) found in vineyards in NE Spain, that water infiltration was mostly influenced by rainfall intensity; in high rainfall intensities soil moisture increased in the first strata without significant increases in depth, but in low intensity rainfall, the soil water content increased in the whole profile, especially when conservation.…”

Chilean dryland areas of the Mediterranean climate region are characterized by highly degraded and compacted soils, which require the use of conservation tillage systems to mitigate water erosion as well as to improve soil water storage. An oat (Avena sativa L. cv. Supernova-INIA) -wheat (Triticum aestivum L. cv. Pandora-INIA) crop rotation was established under the following conservation systems: no tillage (Nt), Nt + contour plowing (Nt+Cp), Nt + barrier hedge (Nt+Bh), and Nt + subsoiling (Nt+Sb), compared to conventional tillage (Ct) to evaluate their influence on soil water content (SWC) in the profile (10 to 110 cm depth), the soil compaction and their interaction with the crop yield. Experimental plots were established in 2007 and lasted 3 yr till 2009 in a compacted Alfisol. At the end of the growing seasons, SWC was reduced by 44 to 51% in conservation tillage systems and 60% in Ct. Soil water content had a significant (p < 0.05) interaction with tillage system and depth; Nt+Sb showed lower SWC between 10 to 30 cm, but higher and similar to the rest between 50 to 110 cm except for Ct. Although, SWC was higher in conservation tillage systems, the high values on soil compaction affected yield. No tillage + subsoiling reduced soil compaction and had a significant increment of grain yield (similar to Ct in seasons 2008 and 2009). These findings show us that the choice of conservation tillage in compacted soils of the Mediterranean region needs to improve soil structure to obtain higher yields and increment SWC.

“…Bates (1973) reported that proline is more sensitive for water stress compared to other amino acids. Proline accumulation in plant tissues depend on, variety and age of plant, kind of stress and intensity of stress (William and Sharon, 1981;Roberto et al;2009). Therefore, proline accumulation in plant tissues is appropriate indicator to evaluate the soil physical and moisture stress of different conditions of soils.…”

Soil physical and water stress conditions adversely affect the biochemical aspects of coconut production. Field experiments were conducted in Madampe and Andigama soil series, to investigate the ATPase activity, starch conversion to glucose and accumulation of proline in leaves, absorption cells and respiratory organs of coconut roots and their interrelationships with respect to soil physical and water stress. After one and half years of the establishment of coconut seedlings in different horizons of both series, the moisture contents at three depletion levels viz.10 kPa to 30 kPa, 10 kPa to 100 kPa and 10 kPa to 1500 kPa were maintained using tensiometers and neutron scatteringtechnique in order to create moisture stress around root zone of coconut seedlings during the dry period. Detailed soil physical analysis showed that soil compaction limits the aeration and available water retention in soil horizons of both series. Evaluation of biochemical properties showed that the highest ATPase activity and starch conversion to glucose in leaves and absorption zone of coconut roots was observed in the B horizon of Madampe series at field capacity moisture level (10 kPa to 30 kPa suction), while the lowest activity was observed in the A horizon of Madampe series and B horizon of Andigama series at high water stress condition (100 kPa to 1500 kPa suction). However, the highest ATPase activity and starch conversion rate was observed in respiratory organs in A horizon of Madampe series. Moreover, the starch and proline accumulation in different parts of coconut seedling positively related with soil physical and water stress conditions (100-1500 kPa) prevalence in 'A' and 'B' horizons of Madampe and Andigama series respectively.
