“…One possible solution for this problem can be than reduction of N mineral availability in the soil, by introducing high N demanding intercrop with high C: N ration, that can promote microbial biomass development (Wei et al, 2017). However, in the winter, there was a reduction of soil mineral N (Oliveira et al, 2016), since there was intense precipitation during the period (average rainfall of 445 mm). Unexpectedly, N application exhibited a positive effect on fruit respiration and a negative effect on pulp firmness, after 90 days of refrigeration storage and 7 days under ambiente conditions at 20 °C.…”

“…During the decomposition of cover crop residues, part of the carbon (C) present in the plant tissue may remain in the soil, especially from residues with lower lability. However, the majority of the C will probably return to the atmosphere as CO 2 , depending on the residue composition and mineralization rate (Oliveira et al 2016a;Reichert et al 2015). Part of the plant tissue N can increase soil available N (nitrate or ammonium), which can be absorbed by mature trees.…”

Cover crop nitrogen (N) cycling has an important role in agricultural production and contributes to peach [Prunus persica (L.) Batsch] N nutrition. This study evaluated black oat (Avena strigosa Schreb) and ryegrass (Lolium multiflorum L.) residue decomposition dynamics, N recovery from cover crop residues, and N compartmentalization in peach tree organs. A 2-year field trial was developed with labeled (3.6-4.0 atom% 15 N excess) cover crop shoot biomass application in a 5-year-old peach orchard. The region's climate is warm temperate (Cfb), and the soil is classified as a Typic Hapludalf. Litter bags with unlabeled shoot residues were also deposited in the orchard to assess biomass, carbon (C), N, lignin, cellulose, and non-structural biomass decomposition dynamics. After 13 months, the leaves, trunk, and roots showed the greatest proportion of N derived from residues (Ndfr) (35.4, 25.1, and 22.4%, respectively) while the greatest concentrations of 15 N and Ndfr occurred in roots <2 mm (0.0376 and 0.94%, respectively). The N derived from cover crop shoots in the second production cycle was similar among tree organs. Ryegrass residues presented the highest decomposition constant (k) values for dry matter, total organic carbon (TOC), cellulose, and lignin. Hence, black oat residues presented a higher half-life (t ½ ) for dry matter, TOC, total N, cellulose, and lignin. The N derived from black oat and ryegrass residues in mature trees was expressively low (<1%) and similar between species. Within organs, the highest Ndfr occurred in peach leaves during the flowering stage, when the greatest residue decomposition rate also occurred. Soil N and plant internal N reserves are the major N sources for newly formed organs, but greater contributions to tree N nutrition may occur with long-term cover crop residue deposition and different plant species.

“…The highest concentration of K in the soil, found in the treatments with the presence of U. ruziziensis mulching on the citrus row, the NT and NT-NH ( Figure 5A), is also reported for other fruit plants such as apple trees, using spontaneous vegetation as a cover crop (Oliveira et al, 2016), and in various no-tillage researches for maize cultivation, using a consortium of Urochloa spp. (Borghi et al, 2013).…”

The management of soil cover plants (intercropping) in orchards can contribute to increase productivity of citrus trees. Thus, the present research aimed to evaluate different planting systems for Tahiti acid lime grafted onto Flying Dragon trifoliate orange, a dwarfing rootstock, at high planting density (1,157 trees ha −1). The study was set up in four tillage systems, using Urochloa ruziziensis as an intercrop species in the orchard, and conducted for 5 years: no-tillage (NT), no-tillage and no-herbicide (NT-NH), minimum tillage (MT) and conventional tillage (CT; without intercropping). Dry matter (DM) production of biomass in the row and interrow of the orchard was evaluated yearly, as well as weed density, soil physical and chemical characteristics, plant water and nutritional status, and fruit yield of trees. Greater deposition of DM of biomass was observed in the row of citrus planting for treatments NT and NT-NH compared to CT and MT treatments, which led to reduced undesirable weed populations. The NT treatment also provided increases of 79% in potassium (K) nutrient concentrations in the leaves of trees and 60% in exchangeable K in the soil surface layer, in the first 2 years evaluated. The maintenance of the Urochloa ruziziensis mulch in the NT system also provided higher soil volumetric moisture content and consequently lower soil resistance penetration and water stress on trees, evidenced by the predawn plant leaf water potential (<1 MPa). Moreover, the NT treatment provided an average increase of 56% of fruit yield from trees compared to the CT treatment during three harvests. This long-term study demonstrated the contribution of the no-tillage system using a favorable cover crop to increase the yield of Tahiti acid lime fruits and maintain the soil quality most required for the sustainability of citrus production.
