Abstract Traditional rice ( Oryza sativa L.) cropping systems under flooding irrigation combined with conventional tillage management are increasing threat due to a loss of soil quality and scarcity water resources, especially in Mediterranean environments. Hence, the development such strategies as no-tillage, application organic amendments, water-saving methods could be vital enhancing sustainability crops. This work tests combination various for growing conditions. It assesses first time...

Clomazone (CLMZ) is one of the most effective and widely used herbicides in rice cultivation, but it has probable risks for environmental contamination. Alternate wetting drying irrigation (AWDI), with or without holm oak biochar (B) amendment, sustainable alternatives to conventional flooding cropping. However, its implementation may induce changes soil characteristics that can strongly affect behaviour CLMZ, although extent will depend on degree severity AWDI. This three-year study first...

Arsenic, Cd, and Pb environmental fate is influenced when the traditional permanent flooding rice production systems are replaced by water-saving soil conservation practices, urging for additional strategies that avoid their bioaccumulation in grain. The aim of this two-years field study was to evaluate effects fresh field-aged biochar on As, bioaccumulation, As speciation, grain produced different growing environments (flooding versus sprinkler conventional tillage direct seeding). Biochar...

A 2-year field experiment was conducted to analyse the effects of fresh and aged biochar on soil properties, as well herbicide effectiveness rice-yield components in a Mediterranean environment. Six managements were used: no-tillage sprinkler irrigation either without (NoT) or with first-year application (NoTB), conventional tillage (ConvT) (ConvTB), flooding (ConvTF) (ConvTFB). The measurements done first (2018) second (2019) years after addition taken determine its effects, respectively....

Traditional rice (Oryza sativa L.) management (tillage and flooding) is unsustainable due to soil degradation the large amount of irrigation water used, an issue which exacerbated in Mediterranean region. Therefore, there a need explore strategies order improve water-use efficiency ensure its sustainability. Thus, field experiments were conducted determine medium-term effects different tillage methods combined with single compost application on productivity, as well food safety semiarid The...

Although alternative practices to traditional flooding rice cultivation urgently need be implemented in water-stressed regions, these can modify soil properties, thereby affecting the environmental behaviour of pesticides. One most extensively used herbicides cropping is clomazone. A field experiment covering two years was conducted evaluate how fresh and aged holm oak biochar (BH) influenced clomazone's after transition from sprinkler irrigation with different tillage systems. The involved...

Imazamox (IMZX) is a persistent herbicide having probable risks for non-target organisms in the environment and water contamination. Alternatives to conventional flooding rice production, including biochar amendment, may induce changes soil properties which can greatly modify environmental fate of IMZX. This two-year study first evaluate how tillage irrigation practices, with or without fresh aged (Bc), that are alternatives production impact IMZX's fate. The treatments were: (CTFI),...

Olive orchards cover over 10 million hectares worldwide, with production techniques undergoing significant changes in the past three decades. The traditional rainfed approach, involving minimal inputs, has given way to irrigated super-intensive systems higher planting density, increased productivity, a greater use of fertilizers and phytopharmaceuticals, total mechanization. Its impact on soil chemical properties remains topic great debate, no definitive consensus been reached. Our main...

Irrigation and tillage systems alone or in combination with organic amendments can strongly influence soil properties, which turn may also modify the environmental fate of any pesticides applied. This study was aimed at determining how amendment composted olive-mill waste (W) influenced leaching, sorption, persistence herbicide clomazone rice field soils under different irrigation management practices. The trial conducted covered 3 years succession, six treatments: by sprinkler conventional...

The olive oil industry produces high amounts of waste, which need to be valorized in a more sustainable way as an alternative its traditional use energy source, with associated CO2 emissions. Rice (Oryza sativa L.) is one the most important crops for global food security; however, cropping systems under flooding lead decrease soil quality, well relevant emissions greenhouse gases (GHG). aim this study was assess GHG emission from rice fields amended composted two-phase mill waste (C-TPOW),...

Olive orchards cover over 10 million hectares worldwide, with production techniques undergoing significant changes in the past three decades. The traditional rainfed approach, involving minimal inputs, has given way to irrigated super-intensive systems higher planting density, in-creased productivity, greater use of fertilizers and phytopharmaceuticals, total mechaniza-tion. Its impact on soil chemical properties remains a topic great debate no definitive consensus been reached. Our main...

The practices (tillage and flooding) used for rice crops are unsustainable, especially in areas characterized by water shortages, such as the Mediterranean region. Therefore, it is necessary to develop sustainable methods order ensure viability of production. However, essential understand effects that alternative management can have on herbicide behavior. In this context, paper describes first field experiment conducted evaluate medium-term different agricultural fate bispyribac sodium...

Traditional rice (Oryza sativa L.) production by flooding is a source of greenhouse gases (GHG), especially methane. The high consumption water, as well the chemical and physical degradation caused these traditional practices in soils, promoting decrease Mediterranean area. aim this study was to monitor GHG emissions net ecosystem carbon balance (NECB) from produced with sprinkler irrigation techniques also assess impact olive mill waste compost (C-OW) application tillage on NECB.
