Special Issue Information

Dear Colleagues,

In orchards, in recent decades an abandonment of traditional cultivation systems has been observed. New cultivation strategies were proposed, mainly to respond to mechanization needs, and now are currently being used in various agro-ecological contexts. These changes in soil management strategies, aimed at reducing farming costs, in some cases have amplified the impact of agro-ecosystems on the environment. Numerous scientific publications report the negative consequences of adopting unsuitable or poorly calibrated soil management strategies with the real needs of the orchard and/or of the soil that hosts it. A loss of chemical and biological fertility, the increase in erosive phenomena, the depletion of water resources, as well as the generalized use of weeding and the pollution of the groundwater, could all be consequences of inappropriate soil management. This Special Issue aims to encourage the dissemination of original scientific works and revisiting contributions, which propose innovative aspects in soil management able to promote greater agronomic, environmental and economic sustainability of the orchard agro-ecosystems. The scientific papers that can be considered for this Special Issue may include several topics, starting with the use of organic soil improvers and/or the reuse of leftovers of cultivation, as well as the use of cover crops in improving soil and crop productivity. Manuscripts that report activities aiming to preserve organic matter and soil water availability, or innovative soil management strategies to support the mitigation of current climate changes, are also welcome.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs).

During tea cultivation, diverse agroforestry is an important and established intercropping measure, with most studies concentrating on ecological service provision and economic returns. However, the response of soil nutrients and microbial community structures in long-term tea plantations with diverse agroforestry intercropping systems is poorly understood. In the present field study (2015), three intercropping agroforestry-tea patterns (Osmanthus-Tea (OT), Michelia-Tea (MT), Osmanthus-Michelia-Tea (OMT)) along with a study control (C) were examined in terms of these two knowledge gaps. Results showed that, in terms of tea cultivation, the OMT system is more suitable than the OT and MT systems. The OMT system significantly increased the total nitrogen (TN, 16.4%), total potassium (TK, 10.5%), available nitrogen (AN, 14.2%), available phosphorus (AP, 26.7%) and soil organic matter (SOM, 28.9%). The OMT system increased phylum Firmicutes and Bacteroidetes abundance by 35.8% and 9.6%. In addition, the OMT system enhanced the abundance of class Bacteroidia (99.5%), Erysipelotrichia (96.9%), Clostridia (93.5%) and Actinobacteria (19.6%), respectively. In general, the phylum bacteria Proteobacteria, Firmicutes, Actinobacteria accounted for the largest proportion of bacteria in all three intercropping systems. In this study, the abundance of Firmicutes, Actinobacteria, Proteobacteria, and Bacteroidetes were positively correlated with AN, SOM and TP. The results of the present study will help to develop a better understanding of the benefits imposed by different agroforestry intercropping systems on nutrient dynamics and microbial structural diversity during tea cultivation.
