“…In the case of anion loads, there was an increase of 11% in Cl − (T0 (5.6 g) and T2 (6.1 g)) and 39% in SO 4 2− (T0 (2.3 g) and T2 (3.2 g)), a removal of 49% of NO 3 − (T0 (4.9 g) and T2 (2.5 g)) and no variations in H 2 PO 4 − concentration. Concerning cation loads, there was a removal of 25% in K + (T0 (1.2 g) and T2 (0.9 g)), of 34% in Ca 2+ (T0 (6.7 g) and T2 (4.4 g)) and 21% in Mg 2+ (T0 (1.4 g) and T2 (1.1 g)) and no variations in Na + concentration (Table 4).…”

“…Nearly all soilless cropping systems in the greenhouses of this area are free-draining, also known as "open", systems that drain directly into the underlying soil [2,3]. As a consequence, this horticultural production system generates a high level of pollution in the environment due to the presence of high concentrations of nitrates and phosphorus in the drainages [4].…”

Abstract:The blending of drainage with water of low electrical conductivity and the sequential reuse of the drainage water are innovative technologies to manage salts in agricultural drainage. Plants of Cucumis melo were grown in coir grow bags, and Rosmarinus officinalis and Cacti spp. were grown in pots with a mixture of sphagnum peat-moss and perlite. In order to assess the effect and evolution over time of these water treatments on plant growth and water management and removal of nutrients, three water treatments were applied over a period of eight weeks. These were: (1) standard nutrient solution; (2) blended water treatment (drainage water blended with water of low electrical conductivity (EC)) and (3) sequential reuse of drainage water treatment. During the experimental growing period, samples of water supplies and drainages generated in each water treatment were collected weekly and from these data water volume and nutrient loads were calculated. At the end of the experiment, leaf fresh weight of rosemary plants decreased under the fertigation with the blended and sequential reuse water treatments. Nevertheless, the application of blended and sequentially reused water allowed for the saving of significant amounts of water and nutrients in comparison to the standard nutrient solution treatment. Considering these advantages, we strongly recommend the setting-up of these water treatments in areas with water scarcity such as in the Mediterranean Basin.

“…The utility of tensiometers in fine-textured soils is limited due to the range of detection; thus, tensiometers are practical in sandy or coarse-textured soils. Details about the use of tensiometers to schedule the irrigation of vegetable crops are provided by several authors, e.g., [99][100][101][102]. SMP thresholds for several vegetables produced in a variety of soil types are also provided [98].…”

Abstract:Agriculture is considered one of the main nitrogen (N) pollution sources through the diffuse emissions of ammonia (NH 3 ) and nitrous oxide (N 2 O) to the atmosphere and nitrate (NO 3 − ) to water bodies. The risk is particularly high in horticultural production systems (HPS), where the use of water and fertilizers is intensive and concentrated in space and time, and more specifically, in the case of vegetable crops that have high growth rates, demanding an abundant supply of water and nitrogen forms. Therefore, to comply with the EU environmental policies aimed at reducing diffuse pollution in agriculture, there is the need for mitigation practices or strategies acting at different levels such as the source, the timing and the transport of N. HPS are often well suited for improvement practices, but efficient and specific tools capable of describing and quantifying N losses for these particular production systems are required. The most common mitigation strategies found in the literature relate to crop, irrigation and fertilization management. Nevertheless, only the success of a mitigation strategy under specific conditions will allow its implementation to be increasingly targeted and more cost effective. Assessment methods are therefore required to evaluate and to quantify the impact of mitigation strategies in HPS and to select the most promising ones.

The book series Advances in Olericulture provides a state-of-the-art account of research in olericulture, the applied life science of production and utilization of vegetable crops. The series focuses on various aspects of vegetable science and technology covering primarily but not exclusively species where the vegetative organ is the economically important component. The series of books spans current topics from sustainable fertilization to organic production; from open field cultivation to advanced soilless growing techniques; from vegetable seed and seedling physiology to vegetable quality and safety; from environmental stresses to phyllosphere communities interaction with vegetables; from postharvest biology and technology to minimally processing of vegetables. The series is designed to present the most advanced scientific information available linking basic and applied research for serving olericulturists, research workers, teachers and advanced students.More information about this series at
