The Media

Nutrient Block is a growing medium product in the form of a square (25 x 25 cm) or cylindrical (diameter = 20 cm, height = 25 cm) made of peat which has been composted, plus adhesive gypsum or tapioca waste. Nutrient Block is designed to support the post mining land rehabilitation program that is now threatening the environmental degradation in mining areas. Nutrient Block products has been proved good for growth because of the media in addition to having physical properties that are capable of storing large amounts of water, contain enough nutrients in the form available to plants,so it can support plant growth. Results of the Nutrient Block application test to Jabon (Anthocephalus cadaba) and Sengon (Paraserianthes falcataria) plants showed that good performance, both plant height and diameter of trees and leaf growth in plants Jabon appear healthy and getting wider.keywords: nutrient block, post-mining land rehabilitation.

Sago Waste

Abstract The use of polybags is not environmentally friendly because the polybags will be thrown away and become trash so the environment will be polluted. One way to reduce environmental pollution is to use compost blocks made from sago waste. Sago waste has nutrients that can be used as plant growth media. One of the developments of growing media from compost is to form it in the form of compact compost blocks. Block compost functions in plant nurseries, stimulating root and leaf growth. The purpose of this study was to determine the effect of the type of block compost sago waste as a growing medium on variations in composition. At the time of planting, seedlings can be directly planted with holes in compost blocks. Seedlings planted in block compost have better growth in the field than seedlings planted in polybags, so that block compost can be considered as an environmentally friendly alternative to polybags.

Hydroponic Systems

Hydroponics is agricultural cultivation without using soil media, where the media can be replaced with husk charcoal or cocopeat media. However, hydroponics is actually the use of nutrients in a solution so that the nutritional needs of the plant are as desired. Accordingly, plant growth can be maximized. The use of media other than soil does not inhibit plant growth because both charcoal husk and cocopeat can store nutrients so that plant growth is not disturbed. This study aims to determine the response of red spinach (Alternanthera amoena Voss.) to Cocopeat and husk charcoal, and also to determine the use of DFT (Deep Flow Technique) and NFT (Nutrient Film Technique) hydroponic systems on the growth and development of red spinach. The method used was RBD where Rockwool media as a control, with 6 treatments and 4 replications. From the research results, the cocopeat media and husk charcoal media gave different results where the cocopeat growing medium was greater than the husk charcoal growing medium and the DFT and NFT systems gave significantly different results where the NFT yield was greater than DFT.Keywords: Hydroponics, Red Spinach, Cocopeat, Husk Charcoal, DFT, NFTABSTRAKHidroponik adalah lahan budidaya pertanian tanpa menggunakan media tanah, dimana media dapat digantikan dengan media arang sekam ataupun cocopeat. namun hidroponik sesungguhnya yakni penggunaan nutrisi dalam larutan sehingga kebutuhan nutrisi pada tanaman sesuai keinginan. Maka pertumbuhan tanaman bisa lebih maksimal. penggunaan media selain tanah tidak menghambat pertumbuhan tanaman karena baik media arang sekam maupun cocopeat dapat menyimpan unsur hara sehingga pertumbuhan tanaman tidak terganggu. Penelitian ini bertujuan untuk mengetahui respon pada tanaman bayam merah (Alternanthera amoena Voss.) terhadap media tanam Cocopeat, dan Arang sekam, dan juga untuk mengetahui penggunaan sistem hidroponik DFT (Deep Flow Technique) dan NFT (Nutrient Film Technique) terhadap pertumbuhan dan perkembangan bayam merah. Metode yang digunakan adalah RAK dimana media rockwool sebagai kontrol, dengan 6 perlakuan dan 4 ulangan. Dari hasil penelitian Media tanam cocopeat dan media arang sekam memberikan hasil yang berbeda dimana media tanam cocopeat lebih besar dari pada media tanam arang sekam dan pada sistem DFT dan NFT memberikan hasil yang berbeda nyata dimana hasil NFT lebih besar dari pada DFT.Kata kunci : Hidroponik, Bayam Merah, Cocopeat, Arang sekam, DFT, NFT

Azomite is a mined, commercially available, hydrated sodium calcium aluminosiliclate soil amendment reported to act as a source of mineral elements. To determine its effect on plant growth, Dendranthema `Connie' rooted cuttings, Malus seedlings, and Citrus seedlings were grown in containers in one of two growing media: ProMix BX or ProMix BX with Azomite (1:1, v:v). Plant height was monitored weekly and after 6 weeks of growth, fresh and dry plant weights of roots and shoots were determined. There was no difference in any of the parameters measured as a result of the addition of Azomite. Any nutritional influence of the Azomite may only be evident in different conditions, e.g., field soil, or over an extended period of time. The Azomite altered the medium's physical properties and therefore bulk density and water-holding capacity of the Azomite were determined for consideration.

Martian Regolith

Perchlorate (ClO4−) is globally enriched in Martian regolith at levels commonly toxic to plants. Consequently, perchlorate in Martian regolith presents an obstacle to developing agriculture on Mars. Here, we assess the effect of perchlorate at different concentrations on plant growth and germination, as well as metal release in a simulated Gusev Crater regolith and generic potting soil. The presence of perchlorate was uniformly detrimental to plant growth regardless of growing medium. Plants in potting soil were able to germinate in 1 wt.% perchlorate; however, these plants showed restricted growth and decreased leaf area and biomass. Some plants were able to germinate in regolith simulant without perchlorate; however, they showed reduced growth. In Martian regolith simulant, the presence of perchlorate prevented germination across all plant treatments. Soil column flow-through experiments of perchlorate-containing Martian regolith simulant and potting soil were unable to completely remove perchlorate despite its high solubility. Additionally, perchlorate present in the simulant increased metal/phosphorous release, which may also affect plant growth and biochemistry. Our results support that perchlorate may modify metal availability to such an extent that, even with the successful removal of perchlorate, Martian regolith may continue to be toxic to plant life. Overall, our study demonstrates that the presence of perchlorate in Martian regolith provides a significant challenge in its use as an agricultural substrate and that further steps, such as restricted metal availability and nutrient enrichment, are necessary to make it a viable growing substrate.

Abstract Utilization of fish waste for producing fishwaste compost (FWC) as a value-added product is preferred to disposing of it in ocean dumping or landfills. This study determined: (i) the effectiveness of FWC as a container-growth medium and N source for greenhouse production of marigolds (Tagetes patula L. ‘Queen Sophia’) and geraniums (Pelargonium x hortorum L.H. Bailey ‘Sprinter Scarlet’) that were drip-irrigated to prevent leaching; and (ii) if leaching was necessary to sustain plant growth. In a 3 by 3 factorial experiment, plants were grown in 100% FWC, 50% FWC:50% Douglas-fir bark (B), and 100% B at 0, 160, and 320 mg (0, 0.0056, 0.0112 oz) N container−1 applied as NH4NO3 every 2 weeks. Under drip irrigation, FWC in the 100% FWC growing medium supplied a sufficient amount of available N up to 7 weeks after transplanting to produce plant quality, shoot growth index (SGI), and shoot and root dry weights comparable to those treated with 320 mg N container−1. In the 50% FWC: 50% B growing medium fertilization with 320 mg N improved plant growth and quality 7 weeks after transplanting. The concentration of inorganic N (NO3 plus NH4) in the 100% FWC declined to very low levels 7 weeks after transplanting. This indicated that FWC used as the sole component of the growing medium was an effective N source for marigolds and geraniums up to 7 weeks after transplant. Compared with no leach plants, irrigation of 100% FWC marigolds with a weekly leaching fraction of about 0.55 did not affect quality, SGI, and shoot dry weight at the time-of-sale, 7 weeks after transplant. The FWC did not have sufficiently high salt content to require minimum leaching to prevent salt injury to the plants.
