Mera iyileştirme uygulamaları ile ilgili
kavramlar, sosyal ve çevresel etkilerin yanında üretim ve ekonomikliği de
kapsamaktadır. Mineral gübrelemesi, meraların verimliliğini arttırabilse de,
gübre uygulama maliyetindeki artış nedeniyle üretim maliyeti artabilir ve sonuç
olarak, net fayda azalabilir. Çalışmada, bozulmuş merada N (0, 60 ve 120 kg ha^-1),
P (0, 60 ve 120 kg ha^-1) ve K (0 ve 80 kg ha^-1)  gübre (NPK) uygulamasının ekonomik
hususlarını vurgulamak için i) kuru ot verimi (KOV), ii) tüketilen ham proteinin
et ırkı sığırlarda can ağırlığa dönüşüm oranı (HPD) ve iii) yeni bir analiz
modeli olarak verim ve nispi yem değeri (NYD) endeksi esasına dayalı toplam
gelirleri esas alan üç ekonomik analiz modeli (EAM) arasındaki farklılıklar
incelenmiştir. Bu amaçla, bozulmuş bir meranın gübreleme ile verimliliğini
artırmak için yürütülen bir araştırmaya ait bir dizi veriler analiz edilmiştir.
Bulgular, en çok 'gelir' değişkeni bakımından farklılık göstermiş ve bu
farklılığın, üç EAM’ın da gelirleri farklı şekillerde tahmin ettiği gerçeğinden
kaynaklandığı belirlenmiştir. Farklı gelir ölçümleri nedeniyle, HPD, en yüksek
net kara sahip olurken, KOV en düşük değere sahip olmuştur. KOV ve yeni bir
görüş olarak NYD esaslı EAM, NPK gübreleri ile hayvansal üretim için kârlı
olacak kadar kaba yem üretilemediğini göstermiştir. Bu çalışma, bir EAM' nin
bir diğerine üstünlüğünü göstermek yerine, farklı verilerle ilgili modelleri
incelemekte ve net faydada belirli bir artış elde etmek için EAM' lerin temel
özelliklerini açıklamaktadır.

Economic analysis of fertilization based on nutritional value of rangeland: A new opinion

Öz

Concepts behind the best
management practices of rangeland improvement include production, economics, as
well as social and environmental aspects. Although revenue in rangelands can be
increased by fertilization, total production cost can increase and as a result,
net benefit may reduce due to increase in fertilizer application cost. This
study examined differences between three economic analysis models (EAM): total
revenue based on i) hay yield (HY), ii) conversion rate of consumable crude
protein to meat on the hoof in cow-calf (CPM) and iii) yield and relative feed
value (RFV) index as a new opinion to highlight the economic aspects related to
the N (0, 60 and 120 kg ha^-1), P (0, 60 and 120 kg ha^-1)
and K (0 and 80 kg ha^-1) fertilization (NPK) in degraded rangelands.
For this purpose, a series of data, gathered from an experiment conducted to
increase the productivity of degraded rangelands by fertilization were
analyzed. The results were most dissimilar for ‘the revenue’ variable and this
difference lies in the fact that the EAMs estimated income in different ways.
Due to the different revenue measurements, net benefit of CPM was the highest,
while that of HY was the lowest. The HAY and RFV models indicate that NPK
fertilizers did not increase forage production enough to be profitable for
animal production. This study does not strive to suggest one EAM over another;
however, it examines the respective models concerning various data and
describes underlying characteristics of EAMs to obtain a given increase in net
benefit.
