Soil respiration is the process of releasing CO2 from the soil into the atmosphere, mainly produced by soil microorganisms and plant roots. Soil respiration is influenced by biological factors (vegetation, microorganisms), environmental factors (temperature, humidity, pH) and also human factors (tillage and herbicides). This research aims to determine: (1) the effect of soil treatment systems on soil respiration in cassava cultivation; (2) the effect of herbicide application on soil respiration in cassava cultivation; (3) the effect of interaction between tillage systems and application of herbicides on soil respiration in cassava cultivation. The treatment was designed as a factorial in Randomized Block Design with 2 factors and 4 replications. The first factor is the soil tillage system (Minimum Tillage, Intensive Tillage) and the second factor is the application of herbicides (non-herbicides, herbicide applications). The results showed that the tillage system and herbicide application had no significant effect on soil respiration and there was no interaction between the tillage system and herbicide application on cassava (Manihot esculenta Crantz.). Soil respiration at 3 months after planting is higher than 6 and 11 months after planting. Soil water content are higher in non-herbicide application at 11 months after planting. Soil temperature is significantly correlated with soil respiration at 3 months after planting. Soil water content, soil temperature and soil C-organic did not affect soil respiration.

The growth rate of Paraserianthes moluccana is effected by the planting medium quality. Biochar is a soil-improving agent that could improve soil quality. This study aimed to determine the effect of biochar made from meranti wood (Shorea spp.) by pyrolysis temperature at 400°C and 600°C and dose at 0 ton/ha, 25 ton/ha and 50 ton/ha factors through the growth rate of P. moluccana. The P. moluccana was planted within 2x2 m in the field. The size of planting holes was 100 x 60 cm, the biochar was placed at a depth of 100 cm to 20 cm, then it was covered with soil so that the root did not interact directly to the biochar. This research used 6 months old P. moluccana seedling, and was planted in field demplot for 8 months. The research used the Split Plot experimental design with 5 treatments and 7 repetitions. Data analysis used Analysis of Variance (ANOVA) and Least Significance Different (LSD). The effect of biochar could be seen since the 4th month of plantation. The results showed that biochar with a dose of 25 ton/ha and pyrolysis temperature of 600°C had a very significant effect on the increment of height and significant on diameter steam increment of P. moluccana; increased the rate of stem height 22.6% and stem diameter 23.6% faster than the control. Further research related to the dynamics of P. moluccana growth with a longer time is needed because the physical properties of biochar change over time.

Earthworms are important soil biota that can be used as an indicator of soil fertility. Soil tillage systems and application of organic mulch will affect the activity of earthworms. This research was aimed to study the effect of tillage systems and the application of in situ mulch, and their interactions on the population and the biomass of earthworms. The study was conducted from April to July 2017 at the Integrated Field Laboratory, Faculty of Agriculture, University of Lampung. The study was arranged in a Randomized Block Design (RBD) in a factorial treatment with two factors. The first factor was the tillage system which consisted of the minimum tillage and the intensive tillage. The second factor was the application of in situ mulch, which consisted of the application of 0 Mg ha-1 or without mulch and the application of 5 Mg ha-1 in situ mulch.The data obtained were tested for homogeneity of variance with the Bartlett Test and its additivity with the Tukey Test. Data were further analyzed for the analysis of variance and for the LSD’s Test at the level of 5%. The relationship between soil temperature, soil moisture content, soil organic-C and soil pH with population and biomass earthworm was tested by correlation test. The results showed that the earthworm population and the earthworm biomass at 80 DAP in the minimum tillage was higher than that of the intensive tillage. The earthworm population for all detected planting stages (before tillage, 40 DAP and 80 DAP) with the of application of 5 Mg ha-1 in situ mulch was higher than that of the application of no mulch. There is no interaction between the tillage system and the application of in situ mulch at 0 DAP, 40 DAP, and 80 DAP. The genus of earthworms found in all treatment plots was genus Pheretima under the family of Megascolecidae.

Unsustainable cultivation techniques can cause carbon loss on farm.Â Â The cultivation technique that is often used by farmers today is intensive tillage. Â Intensive tillage can increase CO2. Steps to reduce CO2 gas emissions, while increasing carbon stored in the soil by implementing agricultural cultivation with conservation tillage system (Olah Tanah Konservasi). The conservation tillage system is able to reduce global warming through absorption of C in the soil, and reduce CO2 emissions. In addition, fertilization can also affect CO2 emissions. CO2 emissions in the soil come from soil respiration. The purpose of this study was to determine the effect of long-term tillage systems on soil respiration, determine the effect of long-term N fertilization on soil respiration, and determine the effect of interactions between tillage systems and long-term N fertilization on soil respiration. The study was arranged in a randomized block design (RBD) consisting of two factors, namely the tillage system and nitrogen fertilization factors. The first factor is the treatment of tillage system (T) namely T0 = no tillage, and T1 = intensive tillage, while the second factor is without nitrogen fertilizer (N0) and high nitrogen fertilizer (N1). The data obtained will be tested for homogeneity by Bartlett Test and additives tested by Tukey Test. Furthermore, the data were analyzed by analysis of variance and continued with a BNJ test of 5% level. Observation of soil respiration was done 4 times, namely -1, 1, 2, 3 days after tillage. The results showed that soil respiration one day before to three days after the soil was treated in intensive tillage (OTI) was the same as the no tillage system (TOT), soil respiration -1 days after tillage to 3 days after tillage on nitrogen fertilization (100 N kg ha-1 ) given in the previous planting season the same as without fertilization (0 kg N ha-1), and there is no interaction between the tillage system and nitrogen fertilization on soil respiration.
