“…In these greenhouses black mulching could be a simple passive system to increase solar heat storage in the soil and improve the air/soil thermal regime during the early stages of crop cycles starting in winter. Bonachela et al (2012) observed a positive effect in soil heat flux, ground net radiation and air and root temperature with the use of black mulch compared to transparent mulch or bare soil.…”

Mid 2011 the proposal "Towards a sustainable and productive EU organic greenhouse horticulture", in short, BioGreenhouse, was submitted.At the end of 2011 COST approved this proposal as COST Action FA1105 (see http://www.cost.eu/COST_ Actions/fa/FA1105 and www.biogreenhouse.org), which builds a network of experts working in the field of organic protected horticulture and aims to develop and to disseminate through coordinated international efforts, knowledge for new and improved production strategies, methods and technologies to support sustainable and productive organic greenhouse/protected horticulture in the EU. In total 27 participating COST countries and two COST Neighbouring countries took part in the Action.This Action offered the framework and funds for experts of the participating countries to meet and to work together in Working Groups concerning the objectives of the Action. The objectives related to climate and energy management where: an inventory of the use of fossil energy in the present organic greenhouse horticulture;to develop guidelines for the reduction of the use of primary energy in different regions; to join available information about reduction of energy use and improvement of productivity; and to evaluate the feasibility of substitutes of fossil energy.Nine experts from different regions worked together on this topic. They have addressed their task with commitment, by reviewing the regulations as they exist on energy use for heating and humidity control in the different regions in Europe; presenting strategies for reduction of energy requirement and to increase the productivity of energy; by reviewing the indirect use of energy and the options for replacement of fossil energy by renewable energy.Together they realised this booklet:"Sensible use of primary energy in organic greenhouse production" I believe this booklet will prove a unique source of information for all people and institutions involved in research in organic protected horticulture; for researchers, students, teachers, consultants and suppliers. This booklet could also serve also a starting point for developing strategies for a climate-neutral organic greenhouse ho...

“…Greenhouse agriculture, based on production and profitability, is becoming widespread in the Mediterranean region, with an increasing socioeconomic impact [1]. The province of Almeria (SE Spain), with 31,034 ha, has the highest concentration of greenhouses, most of which are low or medium cost structures with plastic covers [2,3], dedicated to the cultivation of horticultural species. Conventional greenhouse management practices are characterized, in most cases, by the excessive use of agrochemicals and irrigation water [4,5], which, along with the absence of organic inputs or tillage, tends to make the soil lose quality in the long term [6][7][8][9] and has caused a series of environmental problems associated with nitrate leaching [10,11] or with the accumulation of a huge amount of crop residues at the end of the cropping season [12].…”

The short-term responses of soil quality indicators are important for assessing the effects of new management practices and addressing threats to crop yields in greenhouses. The aim of this study was to assess, during three consecutive cropping seasons, the effect of a sustainable management package (CRTMP)—which includes the on-site reuse of greenhouse crop residues and tillage—in comparison with conventional management, based on fertigation only (CMP), on certain biochemical soil quality indicators and crop yields. CRTMP significantly increased (p < 0.05) the values of total organic carbon (TOC), particulate organic carbon (POC), light fraction (LF), water soluble organic carbon (WSOC), and dehydrogenase (DH) and β-glucosidase (GL) activities at a depth of 0–15 cm, as well as the mean concentration of nitrates in the soil solution. In addition, a significant Pearson’s correlation (p < 0.01) found between the indicators suggested a balanced improvement of soil biological activity and nutritional soil state. Nonetheless, the significant (p < 0.05) increases in the mean concentration of chlorides in the soil solution and electrical conductivity (p < 0.05) increased the risk of salinization, which may have affected the concentration of nitrates in the petiole sap and total production in CRTMP, which were significantly lower than in CMP. Nevertheless, the proportion of premium product was significantly higher in CRTMP, while the proportion of non-commercial production decreased.

“…Plastic film mulch has been widely used in agriculture, especially in arid and semiarid regions, since it can save soil water by reducing evaporation [1] and optimize the light and thermal environments for crops [2][3][4][5][6][7][8][9][10][11]. Accordingly, plastic film mulching can improve seed emergence [12,13], root growth [14,15], nutrient uptake [16], stem elongation [5,11], final yield and water use efficiency [17][18][19][20][21].…”

Modeling the Interaction of Plastic Film Mulch and Potato Canopy Growth with Soil Heat Transport in a Semiarid Area

Plastic film mulch is an important agricultural technology to reduce water evaporation and modify the soil thermal conditions for crop production. The optical properties of plastic film mulch and the crop canopy growth are both key factors impacting soil heat transport in the soil-film-canopy-atmosphere ecosystem. In this study, a process-oriented model was developed to better understand the interaction among the plastic film mulch, potato (Solanum tuberosum L.) canopy growth, and soil thermal conditions. Canopy growth, photosynthetically active radiation transmittance, net radiation, soil heat flux, and temperature were monitored in a two-year plastic mulch field experiment in Wuwei (Gansu Province, China). Results showed that the simulation of daily soil surface temperature had a good performance with 2.8 and 1.5 °C of root mean square error (RMSE) for the transparent film mulch (TM) and black film mulch (BM), respectively. Moreover, the simulation of the daily net radiation and soil heat flux model indicated reasonable fluctuations with potato phenological development with the daily R2 ranging from 0.89 to 0.98 in 2014 and 2015 for the TM and BM treatments. It was shown that the canopy temperature under BM was greater than that in TM treatment, and the maximum value difference could be up to 7 °C during the early potato growing period, which implied that the BM may perform better in modifying the canopy thermal condition. The model could provide heat distribution information for plastic film choosing in potato field to avoid heat stress.
