Brawijaya Universitas (UB) Malang will hold a Focus Discusion Group (FGD) which discusses the pattern of soil fertility around Malang on Tuesday (10/16/2018).

The Faculty of Agriculture’ Chairman of Lecturer Committee Dr. Setyono Yudo Tyasmoro said, the discussion of soil fertility was carried out in line with the increase population of Indonesia which currently reaches 260 million so that the priority of agricultural development is still focused on efforts to increase food production, especially rice, to meet national food sufficiency.

He said, in the discussion the FGD focused on the main strategies that were carried out by intensifying existing lands and extending or finding new paddy fields.

"Intensification is done by increasing the intensity of planting (IP) in existing paddy fields through improvement of irrigation infrastructure, so that the land that has been planted once a year can be increased to twice a year (IP-200) and rice fields that have been planted twice a year can increased to three times a year (IP-300), "he said.

In addition to intensifying or increasing the intensity of cultivation (IP), he said, the government also intensively carried out efforts to find new land for creating into rice fields (extensification).

"This new paddy field finding is an elaboration of the Nawacita Program, where the government plans to create 1 million hectares of new paddy fields in 5 years (2015 - 2019), in addition to increasing food production, as well as increasing the rate of land conversion. "he said.

The rice field printing program was based on records from the Directorate General of Agricultural Infrastructure and Facilities (2018), within 3 years (2015-2017) the government has scored 210,261 Ha of new rice fields.

This achievement is actually still far from the target of Nawacita, which should be 200,000 ha per year.

"The main problem of creating rice field is related to its utilization after construction, in addition to aspects of handling cultivation by farmers, low fertility rates also hinder the achievement of targets to  increase food production," he said.

Low fertility in the new paddy fields has resulted in very low productivity yields that are 2.5 tons - 3 tons per hectare of dry milled rice (GKG).

High acidity is the reason why fertility is low.

In new paddy fields the acidity of the soil is in the range of pH 4.0 to 5.0 where the rice crop requires normal acidity conditions that is pH 6.0 to 6.5.

Therefore, the FGD will also discuss technology engineering which is very possible to do in new paddy fields, one of those is by providing land fertility materials in the form of dolomt. The ideal need for dolomite on non-new lands is 4 tons per hectare.

 Meanwhile, the FGD will take "Sustainable Management of Sour Land" as the theme and invite Prof. Dr. Ir. Syekhfani, MS (FP UB's Professor), Dr. Didy Wuryanto (Head of the Budget and Legal Planning Working Group - BRG), as well as Husnan, SP., MP., Ph.D (Head of the Soil Research Institute - Ministry of Agriculture) as the speaker.
