 หัวเรื่อง:การใช้น้ำทิ้งจากการผลิตแก๊สชีวภาพเป็นปุ๋ยไนโตรเจนสำหรับกวางตุ้ง ที่ปลูกบนดินกำแพงแสน ผู้เขียน:ดร.ศุภมาศ พนิชศักดิ์พัฒนา, ศาสตราจารย์เกียรติคุณ สื่อสิ่งพิมพ์:pdf AbstractIn field trials, effluent from biogas production (EFB) of liquid swine wastes was tested as nitrogen source and as irrigation water for Pak-choy (Brassica campestris var chinensis) grown on Kamphaeng Saen soil. The EFB was applied weekly at 40,000 l/rai (6.25 rai = 1 ha) throughout the growing period. With the designated rate, the total nitrogen content of the EFB was equivalent to 20 kgN/rai (125 kgN/ha). Inorganic fertilizer (IF) in the form of ammonium sulfate at the same rate of N as above was used as the standard treatment. Combinations of halves of the two treatments (1/2EFB+1/2IF) and half of the rate of the EFB irrigation water (1/2EFB+IRR) were set up as the alternative treatment. Consecutively, the field trials were conducted 5 crops in the dry seasons. The results indicated that the crop yield from the EFB plot was equivalent to 85% of that from the IF plot whereas the 1/2EFB+1/2IF could produce crop yield comparable to that produced by the IF. Half of the EFB rate in combination with irrigation water supplied less nitrogen to the crop resulting in low crop yield and low nitrogen content in the plant tissue. In addition, the EFB could be used as an alternative source of water for plant growth. It could substitute the irrigation water as much as 40,000 1/rai/wk (250,000 1/ha/wk) or 280,000 1/rai (1,750,000 1/ha) for the whole growing period. With the mentioned rate, there was no change in some chemical and physical properties of the soil such as pH, electrical conductivity, the contents of P, K, Ca, mg, Cu and Zn, bulk density, available moisture capacity and aggregate size distribution. |
หัวเรื่อง:การใช้อินทรียวัสดุเหลือใช้บางชนิดเป็นปุ๋ยไนโตรเจนสำหรับข้าวโพดหวานที่ปลูกบนดินกำแพงแสน ผู้เขียน:ดร.ศุภมาศ พนิชศักดิ์พัฒนา, ศาสตราจารย์เกียรติคุณ สื่อสิ่งพิมพ์:pdf AbstractFour kinds of organic waste material (OWM) and inorganic fertilizer (IF) namely castor meal (CM), activated sludge cake (AS) from whisky factory, rice straw compost (RSC), effluent from biogas production (EFB) of liquid swine wastes, and ammonium sulfate were tested as nitrogen source for sweet corn planted in Kamphaeng Saen soil series. The amount of application was equivalent to 15 kg N/rai (93.75 kg N/ha). The field trails were conducted consecutively 3 times in the dry seasons. The results at the first crop showed that except the RSC, the corn yield in the sole OWM treated plots was more or less as high as that in the IF plot. With continual application of the OWMs, the tendency of the corn yield was expected to show the result at the decreasing order: AS ? EFB ? IF ? CM >RSC > check (Ch). There were not significantly different in yield between the combination treatments of 1/2OWM + 1/2IF and the sole OWM treatment except in the RSC case. The corn yield in the RSC treated plot could be increased effectively as high as that in the IF if the RSC was used in combination with the IF as 1/2RSC + 1/2IF, In terms of plant nutrients, the contents of total N in grain and straw could be ranked in the following order: IF = EFB = AS = CM > RSC > Ch. In terms of tasseling and silking, application of the OWMs, either by itself or combined with IF, enhanced tasseling and silking dates to become 1-3 days earlier than usual. With three consecutive applications of the organic wastes, there was no change in the soil properties in terms of pH, Eh, and Na content. However, continual application of RSC or EFB, either single or combined with IF, tended to increase K and Mg in the soil whereas the AS slightly increased soil P and soil Ca. For the EFB case, it could be used effectively not only as the N source for the sweet corn, but also it could substitute irrigation water as much as 28,000 1/rai/wk (175,000 1/ha/wk) or 196,000 1/rai/crop (1,225,000 1/ha/crop). |
