Total Soil Nitrogen

Utilization of slurry under the combination with mushroom baglog could be used a potential source for replacing nitrogen fertilizer and improve soil fertility. The purpose of this study was to evaluate the different combination and the level of slurry application combining with mushroom baglog on total soil nitrogen and organic contents, total soil bacteria and fungi, along with the improvement of growth and yield of strawberry (Fragaria x ananassa). The experiment used a complete randomized design with five treatments and five replications. The treatments were A1 (100% inorganic fertilizer application as control), A2 (50% composted slurry and mushroom baglog + 50% in-organic fertilizer), A3 (100% composted slurry and mushroom baglog), A4 (150% composted slurry and mushroom baglog), A5 (50% composted slurry and mushroom baglog + 50% in-organic fertilizer), A6 (100% fresh slurry (uncomposted)), and A7 (150% uncomposted fresh slurry). Results showed that the treatments significantly affected total soil nitrogen, total soil bacteria and fungi, along with the growth and yield of strawberry. The A6 treatment which used 100% uncomposted fresh slurry, showed the highest total nitrogen in the soil (0.23%) and total population of bacteria (7.1 log CFU/g) and the greatest number of strawberry stolons. In term of the number of leaves and total soil fungi, the A3 treatment was the greatest, resulted in number of leaves and total soil fungi at 19.7 per plant and 4.8 log cfu/g x 104. However, the best yield was obtained from the A7 treatment (150% of fresh slurry) at 15.1 kg/ha.

AbstractNitrogen is a common limiting nutrient in soil in part because most N is present as macromolecular organic compounds, not directly available to plants. The microbial community present in soil near roots (rhizosphere) is in many ways analogous to the human gut microbiome, transforming nutrients present in organic substrates to forms available to plants through extracellular enzymes. Many recent studies have focused on the genetic potential for nitrogen cycling by bacteria in the rhizosphere, and on measuring inorganic N pools and fluxes. Between those two bodies of knowledge, there is scarce information on functionality of macromolecular nitrogen decomposing bacteria and fungi and how it relates to life stages of the plant. This is particularly important as many soil bacteria identified in community composition studies can be inactive or not viable. Here we use a time-series of metatranscriptomes from rhizosphere and bulk soil bacteria and fungi to follow extracellular protease and chitinase expression during rhizosphere aging. In addition, we explore the effect of adding plant litter as a source of macromolecular carbon and nitrogen. Expression of extracellular proteases increased over time in the absence of litter, more so in the presence of roots, whereas the dominant chitinase (chit1) was upregulated with exposure to litter. Structural groups of proteases were surprisingly dominated by serineproteases, possibly due to the importance of betaproteobacteria and actinobacteria in this grassland soil. Extracellular proteases of betaprotebacterial origin were more highly expressed in the presence of roots, whereas deltaroteobacteria and fungi responded to the presence of litter. We found functional guilds specializing in decomposition of proteins in the rhizosphere, detritusphere and in the vicinity of aging roots. We also identify a guild that appears to specialize in protein decomposition in the presence of roots and litter and increases its activity in aging rhizosphere, which may imply that this guild targets rhizodeposits or the senescing root itself as a protein source. Different temporal patterns of guilds imply that rather than functional redundancy, microbial decomposers operate within distinct niches.

The present experiment was carried out during the 2010 planting season, atthe Teaching and Research Farms, School of Agriculture, Lagos State Polytechnic,Ikorodu, Lagos State with the view to produce liquid fertilizer fromwater hyacinth (Eichhornia crassipies) and compare its effectiveness withpoultry manure on the performance and yield of fluted pumpkin (Telfairiaoccidentalis). Data on number of leaves and length of main vine 2 weeksbefore fertilizer application (BFA) and 3, 6 and 9 weeks after fertilizer application (WAFA) and the yield at harvesting were collected and subjected to Analysis of Variance (ANOVA) and means compared using Least Significance Difference (LSD). The results showed that at 3 WAFA, water hyacinth had the highest number of leaves (245) and longest length main vine (2.04 cm) and in terms of yield at harvesting, water hyacinth (16.08 kg) was not significantly different (P>0.05) compared to poultry manure (18.13 kg) application. From the study it can be concluded that water hyacinth liquid fertilizer can be utilized as good source of organic fertilizer for the growth of fluted pumpkin and thus serve as veritable means of curbing the menace of water hyacinth on our water ways.

Total Soil Nitrogen

Mixtures of some tropical legumes and Paspalum plicatulum (Michx) cv. Hartley, and stands of P. plicatulum were fertilized with urea at 100 and 200 lb nitrogen an acre a year, and were intermittently grazed by cattle over a period of four years. Soil analyses for organic carbon and for total soil nitrogen in the fourth year of the pasture phase revealed large treatment effects in three of the five replicates. These three replicates which were on a podsolic soil were lower in fertility than the remaining two on a latosolic soil. Soil nitrogen at the 0-3 inch depth in the high nitrogen treatment, and in two Phaseolus atropurpureus D.C. treatments was significantly higher than the control (P<0.05). Organic carbon at the 0-3 inch depth was significantly higher than the control (P<0.05) in the nitrogen treatments and in one of the P. atropurpureus treatments. For both soil nitrogen and organic carbon the Lotononis bainesii Bak. treatment did not differ from the control. There was no significant difference between treatments for soil nitrogen or organic carbon at the 3-6 inch depth though trends were similar to those at 0-3 inches. Organic carbon and nitrogen were closely correlated for all treatments at both depths, and there were no significant differences in the C : N ratio in any treatment. Yields of sorghum grown as a test crop after the pastures were significantly correlated with soil nitrogen values in the three low fertility replicates. A high correlation (r = +0.976) also existed between yields of nitrogen obtained in the pasture phase and test crop yields of nitrogen for all treatments except L. bainesii. Reasons for the apparent lack of improvement in soil nitrogen and carbon on the higher fertility replicates and for the poor test crop yields following L. bainesii are discussed.

The productivity of organic farming has mainly focused on its relative crop yields than the proportions of organic matters in soil. However, organically cultivation changes crop yields at the same time it depends on types of crops grown. Here, we provide a pot experiment on the rooftop in Latin Square Designs (LSD) with a Diamant variety of potato and four treatment combinations to evaluate variety’s growth and yields. T0: Control, T1: 100% organic fertilizer, T2: 75% organic fertilizer+25% soil and T3: 50% organic fertilizer+50% soil was used for the present study with three replications. Our analysis showed the tallest (23.78 cm) plant was in T2 followed by T1 and T3 (23.37 cm and 23.14 cm, respectively). T2 produced the maximal (76.44) number of leaves per stem followed by T2 and T3 (73.44 and 74.11, respectively). T1 generating the maximal number (6.89) of tubers per hill was significant than all the other treatments. The highest weight (19.13 gm) per tuber per hill was examined in T2 followed by T1 and T3 (17.05 gm and 12.91 gm, respectively). T2 produced the utmost tuber length (3.78 cm) followed by T1 and T3 (3.39 cm and 3.23 cm, respectively. 75% organic fertilizer+25% soil has concluded the potential to be grown successfully and the most suited treatment for production of potato (Diamant) in coastal areas of Bangladesh.

This study aims to determine the effect of the combination of AB mix nutrients with liquid organic fertilizer (LOF) of tofu liquid waste on the growth and yield of lettuce plants and to obtain the best combination for the growth and yield of lettuce hydroponically. This study used a non-factorial Randomized Block Design (RBD), consisting of a comparison of nutritional treatments, namely: N1 = 100% AB mix + 0% LOF of liquid waste tofu, N2= 75% AB mix + 25% LOF of tofu liquid waste, N3= 50% AB mix + 50% LOF of tofu liquid waste, N4= 25% AB mix + 75 % LOF of tofu liquid waste, N5= 100% LOF of waste liquid tofu which consists of 4 replications. Parameters observed were plant height, number of leaves, leaf length, leaf width, root length, fresh weight, root volume and weight fit for consumption. The results showed that the administration of 50% AB mix + 50% LOF of tofu liquid waste and 25% AB mix + 75% LOF of tofu liquid waste showed results that tended to be the same but the results of the combination of 75% AB mix + 25% LOF of tofu liquid waste were higher. On the parameters of the number of leaves is 11.12 strands, fresh weight is 66.40 g and suitable weight for consumption is 58.31 g.
