“…Fruitfulness (number of fruit setting per 100 flower clusters) was measured by counting all flower clusters and following fruit setting from each tree in June and July, respectively, during the third and fourth experimental years (2016–2017). Apple yield was also determined as the number of fruit per day and average fruit weight.…”

“…Apple yield was also determined as the number of fruit per day and average fruit weight. For the measurement of starch pattern index, as a standard method for measuring the quality of mature apple fruits, 15 apples per treatment plots were sampled and potassium iodide adsorbed area was assessed on a 1–10 scale basis using an image analysis system . Usually, starch in apple fruit reaches its accumulation peak prior to maturation, and higher starch presents higher quality and durability of apple fruits …”

“…The production of commercial apple has attracted more attention during last two decades, particularly in southwest Asian countries including Iran, categorized as the fifth largest apple producer with 130 291 ha commercial apple orchards . Nevertheless, productivity of the apple trees is relatively low (12.8 t ha −1 , ranked ninth in productivity), principally affected by the replantation of apple orchards, most likely due to apple replant disease (ARD) as the main disease in replanted orchards, and overuse of synthetic macro‐ and micro‐fertilizers as well . ARD is a soil‐borne disease that affects replanted young apple trees, with symptoms of suppressed plant growth, lower yield and poor fruit quality .…”

BACKGROUND Numerous studies have addressed the positive effects of organic amendments on soil and plant productivity under short‐term field studies. However, to date, few studies have been conducted on the effects of organic amendment on the orchards where high nutrient bioavailability is required. This study deals with the effects of biochar and compost on soil quality, growth and yield of a replanted apple orchard in the northeast of Iran. RESULTS Biochar+compost application resulted in 37% and 300% higher soil total organic carbon and available phosphorus content, respectively, during the first 3 years of experimentation compared to control. Similarly, trunk diameter and shoot number of apple trees increased 23–26% by the end of the first year. Nevertheless, there were no significant changes in fruitfulness, fruit weight or starch pattern index as productivity indices. CONCLUSION Biochar and compost were beneficial in improving soil quality, mainly by increasing soil nutrient content and decreasing soil bulk density, and in increasing plant growth at early growth stages of apple orchards. However, they failed to enhance overall yield and fruit quality, most likely due to their limited ability to suppress apple replant disease. © 2018 Society of Chemical Industry

“…Adding mineral fertilizer, e.g., with P, (Sewell et al, 1988), as well as managing ground cover by adding compost or even biochar, may induce increased biocontrol properties of soils including a reduction of nematodes causing root lesions. Fertilization may thus affect ARD severity in nutrient-limited soils (van Schoor et al, 2009), but frequently failed to replace fumigation for replanting in temperate climates (St. Laurent et al, 2008;Mazzola and Manici, 2012;Glisczynski et al, 2016;Peruzzi et al, 2017).…”

“…This is especially of importance where low rainfall imposes constraints on plant growth and development (Schlesinger et al, 2015, Abideen et al, 2017. The social demand on agriculture is not only to produce high-quality food for a growing world population but farming also has to deal with careful use of resources and the mitigation of climate change (von Glisczynski et al, 2016). The use of biochar (charcoal produced from biomass by pyrolysis in a low-oxygen environment for use as a soil amendment or carbon sequestration) as a soil amendment could help to achieve all these requirements.…”

Characterization of pyrolysis products derived from three biological wastes and their effect on plant growth and soil water retention

Summary.Over two-thirds of Morocco can be classified as semiarid, arid and desert with low and variable rainfalls. While the country is subject to frequent drought, groundwater resources are predominantly consumed by irrigated agriculture leading to the depletion of water resources and degradation of soil quality. Application of bio-resources wastes to soils after pyrolysis process is well documented to help retain water and nutrients in soils. In this study, three bio-resources wastes derived from argan shells, wood chip, a blend of paper sludge and wheat husks are characterized for physical and chemical properties. To determine the potential impact of salt stress and toxic substances the second part of this study focused on the effect these bio-resources wastes have on germination of salad and barley respectively. The three bio-resources obtained from different biomass showed some unique properties compared to the soil, such as high electrical conductivity (EC), high content of K, Na and Mg, low content of heavy metals. Moreover, the water holding capacities increased with increasing application of bio-resources wastes. Concerning the phytotoxic tests, no negative effect was observed neither for salad (Lactuca sativa L.) nor for barley (Hordeum vulgare) indicating that the three bio-resources could be safely used for agriculture. Collectively, the use of these bio-resources wastes as a soil amendment is anticipated to increase both water and nutrient and could provide the potential for a better plant growth mainly in semiarid, arid and desert climatic conditions like the case of Morocco in which the agricultural practices reserve a majority of the water resources to be used for irrigation.
