“…Therefore, high tree productivity depends on low weed competition (Granatstein, 2003;Weibel and Häseli, 2003). In organic apple orchards, floor vegetative cover can be used to improve soil fertility and moisture retention, control soil erosion, increase yield, and develop fruit quality and storage potential, as well as reducing weed competition (Granatstein and Mullinix, 2008;Stefanelli et al, 2009;Zoppolo et al, 2011).…”

In an organic apple orchard, standard mechanical cultivation was compared with four different orchard floor management systems (OFMS): acetic acid (V), living mulch (L), a sandwich system during the growing season (SSS), and a sandwich system during the whole year (SSW). The effects of these OFMS on weed management, soil conditions, tree growth, tree yield, fruit quality, and fruit storage potential in a cool climate were evaluated. Acetic acid treatment showed good weed suppression without any amendatory effect on soil conditions, fruit quality, or tree performance. The L and SSS systems increased soil respiration, decreased tree vigor, and improved fruit quality, but had no sufficient influence on weed competition and thus decreased fruit yield. Only SSW gave better weed control, higher soil respiration, and acceptable tree growth with no yield reduction. Fruit from this system also showed better quality at harvest than fruit from other OFMS and maintained this good quality during storage. A 6-week weed-free period from late May to mid-July gave the highest apple yield in two OFMS (SSW and V).

“…In order to achieve the highest apple yield without compromising other objectives, some horticulture practices will be employed. However, there are many yield-limiting factors for apple production, such as tree age, mulch [45,46], crop load [47], and rootstocks [48]. In the present study, combined reflective film and other inputs was an effective approach to improving yield (Table 1).…”

Transforming apple production to one with high yield and economic benefit but low environmental impact by improving P-use efficiency is an essential objective in China. However, the potential for multi-objective improvement for smallholders and the corresponding implications for horticultural practices are not fully appreciated. Survey data collected from 99 apple producers in Quzhou County of Bohai Bay Region were analyzed by the Pareto-based multi-objective optimization method to determine the potential of multi-objective improvement in apple production. With current practices, apple yield was 45 t ha−1, and the economic benefit was nearly 83,000 CNY ha−1 but with as much as 344 kg P ha−1 input mainly from chemical fertilizer and manure. P gray water footprint was up to 27,200 m3 ha−1 due to low P-use efficiency. However, Pareto-optimized production, yield, and economic benefit could be improved by 38% and 111%, respectively. With a concurrent improvement in P-use efficiency, P gray water footprint was reduced by 29%. Multi-objective optimization was achieved with integrated horticultural practices. The study indicated that multi-objective optimization could be achieved at a smallholder scale with realistic changes in integrated horticultural practices. These findings serve to improve the understanding of multi-objective optimization for smallholders, identify possible constraints, and contribute to the development of strategies for sustainable apple production.

“…For apple orchards on the Loess Plateau region, Wang et al . () found that the average soil organic matter (SOM) content of 12.6 g/kg was typically too low for the levels needed (>20 g/kg) for adequate apple growth and high yield (Zoppolo et al ., ). Furthermore, SOM levels in apple orchards showed a downward trend with increasing orchard age, due to the low levels of organic matter (OM) addition and a management regime that includes removal of weeds, dry branches and fallen leaves from the trees.…”

We investigated the effects of compost (CM), made from poultry and cattle manure with spent mushroom substrate, plus chemical fertilizers (CFs) on soil organic carbon (C) and nitrogen (N) fractions in silty loam soil of the Loess Plateau. Eight fertilizer practices were applied in a 7‐year‐old ‘Red Fuji’ apple (Malus domestica Borkh.) orchard for 360 days. Compared to CM alone, CM–CFs decreased slightly soil total organic C but increased total N by 4.3–11.6%. Notably, CM–CFs increased soil microbial biomass C (MBC) by 2.7–26.5% and microbial biomass N (MBN) by 7–13.7%. Soil water‐soluble carbon (WSC) was increased by 20.7% and 19.2% when 2% CM plus N and phosphorus (P) (2%M–NP) and 4% CM plus N and P (4%M–NP) were applied, respectively. Whereas 0.5% CM plus N and P (0.5%M–NP) increased WSC by 9.3% on day 30 but decreased it by 7.2% from 30–360 days. Hot water‐soluble C increased by 13.1–14.6% from 0–180 day, but thereafter, the effect disappeared. Compared to CFs, CM–CFs increased MBN by 35.1–115.6%, and increased alkali‐hydrolyzable‐N by 3.5–55.8% over 180–360 days of incubation. Additionally, CM–CFs promoted N mineralization, increasing NH4‐N and NO3‐N contents. Based on the changes in C and N fractions and available nutrients, 2%M–NP (45 t/ha of CM plus 450 kg/ha of N and 157.5 kg/ha of P) may be the optimal fertilizer strategy for stimulating soil microbial growth and activity, and enhancing nutrient cycling for apple growth.
