Home gardeners living in areas with alkaline water sources do not have easy or economically affordable means of acidifying irrigation water for vegetable production. One solution for achieving optimal vegetable yields using alkaline irrigation water is to grow the vegetables in a modified medium. To date, no medium on the retail market suits such growing needs. Therefore, medium recipes with varied levels (0, 4, or 8 lb/yard3) and sources of calcium [dolomitic lime, calcium sulfate (CaSO4)] and magnesium [dolomitic lime, magnesium sulfate (MgSO4)] were tested using an alkaline irrigation on ‘Oakleaf’ lettuce (Lactuca sativa), ‘Earliana’ and ‘Salad Delight’ cabbage (Brassica oleracea var. capitata), and ‘Snow Crown’ cauliflower (Brassica oleracea var. botrytis) crops. Additionally, crops were grown in two environments, under a high tunnel and on a nursery yard. High tunnel and nursery yard sites were used to test media performances in the presence of, and eliminating, rainwater to simulate container-grown vegetables growing in both a home garden situation and a commercial greenhouse production situation. The base mix of all media treatments in the study was 80 bark : 20 peat and fertilized with 12 lb/yard3 slow-release fertilizer at a rate of 1.8 lb/yard3 nitrogen (N), 0.5 lb/yard3 phosphorus (P), and 1 lb/yard3 potassium (K). This initial fertilizer application was incorporated to each medium before filling containers. Four treatments were tested against a commercially available medium, industry standard (IS) treatment (a commercially available bagged medium), and a control medium [treatment C (no supplemental calcium or magnesium fertilizer)] by supplementing the base mix with the following fertilizer levels: 4 lb/yard3 each of CaSO4 and MgSO4 (treatment 1); 4 lb/yard3 dolomitic lime (treatment 2); 4 lb/yard3 each of dolomitic lime, CaSO4, and MgSO4 (treatment 3); 8 lb/yard3 dolomitic lime (treatment 4). Media treatments 1 through 4 outperformed the IS and C media treatments in nearly all crops. All crops grown on the nursery yard, and cabbage grown under the high tunnel, had greater yields when grown in medium treatment 3, compared with the IS and C media treatments (P ≤ 0.05). All crops grown in medium treatment 2 on the nursery yard produced greater yields than the IS and C media treatments (P ≤ 0.05).

Problems arising from silica sand mining are decreasing soil fertility, as well as the presence of high heavy metals such as Fe and Al, which inhibits the growth of revegetation plants. The purpose of this study was to analyze the response of the growth of balsa seedlings (Ochroma bicolor Rowlee.) on silica sand post-mining media treated with MycoSilvi, compost, and lime and determine the most optimal combination of MycoSilvi, compost, and lime treatment. This study uses a completely randomized design (CRD) with a split-plot design with 3 treatment factors, namely the addition of MycoSilvi, compost, and lime. Each treatment consisted of five replications. The results showed that the planting media that were not treated (control) was not able to support the growth of balsa seedlings. The interaction of MycoSilvi, compost, and lime significantly affected the height, diameter, biomass, and percentage of mycorrhizal colonization parameters, and significantly affected the plant chlorophyll content. The combination of MycoSilvi type 1 treatment, namely Glomus mosseae and lime (C0K1M1) type, resulted in the highest total growth rate, diameter, biomass, and colonization percentage compared to other treatments. The addition of lime and compost to the growth medium can reduce the degree of mycorrhizal dependency of balsa seedling.
