Abstract

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.

Abstract

Agregat tanah merupakan kesatuan partikel tanah yang melekat satu dengan yang lainnya lebih kuat dibandingkan dengan partikel sekitarnya. Kemantapan agregat tanah dapat didefinisikan sebagai kemampuan tanah untuk bertahan terhadap gaya-gaya yang akan merusaknya. Agregat tanah yang mantap akan mempertahankan sifat-sifat tanah yang baik untuk pertumbuhan tanaman sehingga dapat meningkatkan hasil produksi cabai merah (Capsicum annuum L.). Penelitian ini bertujuan untuk mengetahui dosis pupuk hayati dan frekuensi pemberian pupuk alkalis terbaik terhadap kemantapan agregat tanah dan produksi tanaman cabai merah (Capsicum annuum L.). Penelitian menggunakan Rancangan Acak Kelompok (RAK) yang disusun secara faktorial (3x3) dengan 3 ulangan dengan faktor pertama 3 taraf dosis pupuk hayati yaitu 0 l/Ha, 4 l/Ha, dan 8 l/Ha dan pemberian pupuk pelengkap alkalis yang terdiri dari perlakuan tanpa pupuk pelengkap, pemberian pupuk pelengkap 1 kali/minggu, dan pemberian pupuk pelengkap 2 kali/minggu sebagai faktor kedua. Hasil penelitian menunjukan bahwa Pemberian pupuk hayati hingga 8 l/ha berpengaruh terhadap meningkatnya kemantapan agregat tanah, bobot kering akar, dan bobot buah per petak secara signifikan. Pupuk alkalis dengan interval aplikasi 2 kali per minggu meningkatkan bobot kering akar dan bobot buah perpetak. Sedangkan interaksi kedua faktor hanya berpengaruh pada bobot buah per petak.

Abstract

Unsustainable cultivation techniques can cause carbon loss on farm.   The cultivation technique that is often used by farmers today is intensive tillage.  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.

Abstract

Soil respiration is an indicator of the activity of microorganisms in the soil. The treatment of soil tillage system and the use of organic mulch given to the soil will affect the activity of soil microorganisms. The research aims to study the effect of soil tillage systems, application of in situ mulch, and the interaction between both in soil respiration. This research was conducted from April to July 2017 at the Integrated Field Laboratory, Faculty of Agriculture, University of Lampung, using a Randomized Block Design (RBD) factorially prepared with two treatment factors. The first factor is the soil tillage system (T), which consists of minimum tillage (T0) and conventional tillage (T1). The second factor is the treatment of mulch (M), which consists of no mulch (M0) and the application of in-situ mulch 5 t. ha-1 (M1). The data obtained were tested for various homogeneity by the Bartlett test and additivity by the Tukey test. Data were analyzed by analysis of variance and continued with LSD test at a 5% level. The relationship between soil temperature, soil moisture content, soil organic matter, and soil pH with soil respiration was tested by correlation test. The results showed that the soil tillage system and application of in-situ mulch had no significant effect on soil respiration, and there was no interaction between the soil tillage system and application of in-situ mulch in soil respiration on observations before tillage, 1 day after planting (HST), 41 HST, and 88 HST. There is no correlation between soil temperature, soil moisture content, soil organic matter, and soil pH with soil respiration on pre-tillage observations, 1 HST, 41 HST, and 88 HST.
