The application of stabilized organic matter to the soil is essential for the sustainability of a production system. Bokashi is a biofertilizer produced by the aerobic decomposition of organic matter that contributes to the conservation of soil fertility. The objective of this study was to evaluate the effect of bokashi improved with rock phosphate on a curled parsley crop (Petroselinum crispum [Mill.] Fuss var. crispum) under organic management. The process to prepare bokashi at 9% rock phosphate (BP) and without rock phosphate (BK) was evaluated in all treatments at the same temperature, pH, electrical conductivity, and moisture content. Afterward, the effect of applying bokashi on potted curled parsley was evaluated for 10 treatments and 5 replicates. Treatments consisted of three rates (10%, 15%, and 30%) of three P fertilization sources: bokashi with rock phosphate added to the process (BRE), bokashi without rock phosphate (BSR), bokashi without rock phosphate in the process plus rock phosphate added to the pot (BRM), and a control without bokashi (B0). The chlorophyll index, dry matter (DM), foliar P content, and soil available P were evaluated after harvest. The addition of rock phosphate to the compost increased soluble P content by 17.7% and nearly doubled soluble Ca. The BRM treatment at 30% obtained the highest chlorophyll index and BRE at 15% had the maximum DM value. Treatments with bokashi at 30% obtained the highest foliar P content and soil available P. All treatments, except BSR at 10%, improved the chlorophyll index and DM. The evaluated parameters did not vary according to the type of bokashi, but responded to different rates.

Legumes as green manure allow adding N from the air to the soil through their biological fixation. The objective was to evaluate the effect of legume crops as green manure at the beginning of the rotation on soil quality and their N input to the following onion crop (Allium cepa L. var. cepa). Five crops were sown: faba-bean (Vicia faba L.), field pea (Pisum sativum L.), oat-vetch mixture (Avena sativa L. + Vicia atropurpurea Desf.), white lupin (Lupinus albus L.), and oat as control treatment, with four replicates. Prior to sowing soil was prepared with 20 Mg ha -1 compost and 715 kg ha -1 rock phosphate. Then, at 50% grain filling stage these crops were incorporated as green manure to the soil, followed by the onion crop. Biological N fixation (BNF) by 15 N natural abundance technique parameters of green manure, yield, leaf N content of the legumes and onion, and soil bio-physicochemical properties were measured and analyzed by ANOVA and Tukey's test for mean separation (P ≤ 0.05). Faba-bean treatment had the highest BNF (388 and 369 kg N ha -1 fixed in 2017 and 2018, respectively). For onion yield, just faba-bean and oat-vetch in 2018 reached the Chilean mean yield with 54.39 and 49.08 Mg ha -1 , respectively. Control treatment yield was not significantly different. Leaf N content in onion remained within a normal range in all treatments. Adding green manure together with compost to the soil improved soil N and K contents.
